The ROKs; Republic of Korea Soldiers in Vietnam


  President Johnson did not want the war to broaden. He wanted the North Vietnamese to leave their brothers in the south alone.

                               Recruited Allies

ROKs preparing for action.

Many American GI’s who served in Vietnam had contact of one kind or another with troops from South Korea, commonly referred to as the “ROKs”. The Republic of Korea, a staunch ally of the U.S., sent some 335,000 troops to fight in South Vietnam from 1965 to 1973. Of those 335,000 troops some 5,500 were killed in action, while over 11,000 were wounded. Though the South Korean Army contributed most of those troops, members of South Korea’s Marines, Air Force and Navy also participated in the war.

Johnson desperately needed support for the war.

As one of the participants of Lyndon B. Johnson’s “Many Flags” campaign, South Korea became the largest foreign presence in Vietnam, after the United States.


                                Controversies Arise

The South Korean government was not anxious to send troops to Vietnam but did so for economic reasons, and more importantly, because it feared the United States would transfer many of its own troops from South Korea to Vietnam, if they did not comply with Johnson’s request. Even so, South Korea was granted specific sums of money for each South Korean troop deployed to South Vietnam, along with regularly scheduled “general” payments to the South Korean government for the duration of the war. As part of the agreement, the U.S. also agreed to purchase many war materials from South Korea and contracted with South Koreans for many other war related services during the course of the war. These activities prompted many U.S. politicians and citizens to decry the actions as nothing more than the hiring of mercenaries to fight Johnson’s war, as well as shelling out poorly veiled bribes for foreign support.

The ROKs held no sympathy for the enemy.

Other problems arose with the South Vietnamese military who largely detested the Koreans, believing them to be interlopers and bullies.

South Korean Soldiers and Marines, known for their toughness were accused of various atrocities throughout the war, and to this day, the government of Vietnam is still attempting to press charges against the South Koreans for actions that occurred during their time there.



                   Admiration and Respect, from the U.S. Military


The ROKs aided the U.S. military in every way.

Despite the controversies surrounding their participation in the war, the U.S. military held the South Koreans in high regard and U.S. GI’s who served with the ROK’s (me included) hold many favorable memories of them.

The two ROK army divisions that served in Vietnam were the “White Horse Division” and the “Capitol Division”, more commonly known as the “Tiger Division”.

My involvement with the Koreans was with the “Tiger Division” which had two camps just outside the Phu Cat Airbase perimeter.

The Phu Cat perimeter was frequently probed by VC and the NVA.

At Phu Cat, the “Tigers” conducted both passive operations, including defensive positions along our perimeter, as well as aggressive operations including search and destroy patrols in the general area surrounding the Phu Cat Airbase.

As more and more elements of the 173rd Airborne were pulled back during President Nixon’s Vietnamization program, the Phu Cat Airbase assumed more and more responsibility for its own protection. Security police and augmantees (volunteers) patrolled the base perimeter 24 hours a day. The local Vietcong would often probe the perimeter, sending sappers in to inflict damage whenever they could. While Air Force base defenses performed the passive defense very well, they were not trained or equipped to go out on patrols, seeking out Vietcong and North Vietnamese soldiers. The ROKs, on the other hand, performed that task very well.


                                    The ROKs and Me

The main ROK compound outside Phu Cat Airbase southern perimeter.

I first became associated with the ROKs when I spent time in their main camp outside of our south perimeter learning the martial art of Tae Kwon Do. Larger and stronger than the Vietnamese, the ROKs were tough, disciplined and extremely dedicated in the application of their practice of karate. Watching them as they trained and sparred we became quite impressed with their physical prowess. Few Americans could match their abilities in hand to hand fighting.

I eventually earned a yellow belt in Tai Kwon Do, but never took it any farther; I was not what you would call a “natural” in that endeavor. Some of my peers became quite enthralled with the martial art, earning various degrees of black belts. They would spend their off duty hours with the Koreans, training and sparring. Our non-com at the time would often chide us over our involvement in the activity. He called us “chimbee artists” after the sound we made when we executed our moves.

When I had about three months left of my tour of duty in Vietnam, I began spending much of my time in the Korean bunker just outside of our Western perimeter. My two best friends whose tours were over had already left Vietnam. With Nixon’s Vietnamization program in full swing, my previous duty station required a skeleton crew only, leaving me a ship without a navy, so to speak. Recruited for other duty, I spent about one month loading and unloading cargo on C-130 and C-47 aircraft. I flew all around the Central Highlands of Vietnam during that time. That was great duty for me; I especially enjoyed my one-week stay at Nha Trang, which had a beautiful beach for swimming and even surfing.

However when my flying days ended, I still had little to do and was pretty much in charge of my own activities. I took my R & R to Hong Kong (much enjoyed) but when I came back, I still had no workstation to report to on a regular basis so I started hanging with my old friends, the ROKs.

The ROK bunker where I spent most of my last two months in-country.

The ROKs on our Western perimeter maintained a small, less than platoon size bunker, and because of my earlier association with them, I now found myself charged with making sure they had everything they needed that our Airbase could provide. (They finally found something for me to do so I’d leave them alone) I felt this was worthy duty and I also enjoyed it.

Each morning I would walk over to the ROK compound just outside of our Western perimeter, and spend most of the day there. The ROK Lieutenant in charge would greet me on arrival after which we would discuss any number of topics. Protocol was important to the ROKs and it was necessary for me to spend whatever time the Lieutenant required, discussing whatever subject he liked. As a recent convert to Christianity, the Lieutenant liked to discuss religion. Being a Luke-warm disciple of religion, my participation in the discussion was based primarily on manners and military protocol.

Kim Jun-Ki and myself

The rest of my day at the Korean compound would be spent in any number of ways at my new duty station. One of the Korean soldiers and I became close friends over time and we were inseparable during my time there. Kim Jun-Ki and I fished and swam in the little river that ran by their compound, and shared family histories as well. He had a sister named Jun-Ja and he hoped to engineer a marriage between us. Another time, another place perhaps, but I wasn’t ready for a marriage based on correspondence, so I held him off on that one. Kim and I kept in contact for several years after we both left Vietnam and after all these years I still think of him often, hoping he prospered and did well in life.

For reasons of self-preservation, the local VC usually spared the ROK compound from the mortar and rocket attacks the airbase was subjected to. During my stay with the Koreans, I recall only one or two mortar attacks and the mortars that fell were well short of our little bunker. It was my opinion that the mortars were intended for the airbase and just fell short.

The ROKs went out on patrol about three or four times a week. They would usually patrol the mountains to the west of our base, known as the Phu Cats. The lieutenant often teased me about going out on patrol with them…at least I thought he was teasing until the day he told me it was time for me to go. Not wanting to lose face, I grabbed my gear and went out on the patrol. My first patrol was fearful, though fortunately for me it was not one of the long-range patrols up in the Phu Cats, but rather just a short two-hour jaunt outside the airbase perimeter. On this particular mission, our patrol encountered no enemy and my short career as a “grunt” during that time left me unharmed. (God bless the grunts!)

Before I left Vietnam, my ROK friends held a celebration on my behalf, including fresh fish from the river, Korean OB 10 beer, and, of course, plenty of kimchee. To this day, I fondly remember all of my days and nights with my Korean friends, I still have a fondness for Kimchee have converted some family members and friends and bring some home now and then.

  1. I served with the ROK in Korea in 67-68.

    Great soldiers.

    While in a field hospital, a North Korean soldier, was in a bed opposite from me guarded by two American MP’s. When he was released by the Americans to South Korea, they hung him soon afterwards. Tough cookies.

    Google “The Second Korean War.”

    1. I was with the Roks from 1968/1969. I was a radio operator with the 54th signal. Seen more then most. alive today because of them.

    2. I was stationed at the 1st Regiment ROK Cap Tiger Division outside the front gate of Phu Cat Air Base.

      Ground Radio Operator USAF!

  2. joe I was an augmentee for 30 days in feb mar 1969 and got to meet many Koreans too. one incident I bought an electric fan for a rok at the bx when I gave him the fan he reimbursed me and next stop arrested by security police spent a couple hours in custody until the capt bailed me out, I would have done it again really appreciated them as I was at phu cat may 1968 to oct 1969 after my extended tour cut a little short due to I went home when my dad died 2 weeks before my 21st birthday

    1. Wow, that’s the Nam, for sure Dan. Glad you came out OK, good hearing from you. Stay in touch.

  3. I supplied the White Horse with batteries and inner tubes from my outside storage yard at Cam Rahn Bay—no paperwork.
    They supplied me with Korean beer—impossible to dent those cans.
    Outstanding convoy escort troops to visit Tiger Division friends outside DaLat and Ban Me Thout. In ambushes, ROKs stopped, ran out, came back with ears and

  4. I never heard of the ROK until I took Tae-Kwon-Do. I found out that the founder (Master Bu Kwang Park) was a Vietnam-era ROK soldier trained directly by General Choi, and he visited each school. I decided to “spar” him as a third degree, and he literally paralyzed my entire body and caused me to slump to the floor in a single punch. I’ve been gored by a 2140 lb hereford bull’s horn before, and it didn’t even feel a tenth as bad as getting punched by him.

    1. I was a ground radio operator detached to 9th ROK, The White Horse Division, 1970-1971 in support of Cutie FACs. Whether at Division or one of the regiments, you could see the parade ground filled each morning with Korean soldiers practicing exercising with their Tae-Kuon-do with all the oomphs, ahs, and grunts that goes with it. I may make light of it, but not of them. I am proud and thankful for my opportunity to serve with great soldiers – and, I thank them for keeping my butt safe whenever I was with them. I was invited to take Tae-Kwon-Do, but stupidly (in handsight) I chose women, booze, and partying for my spare time…

      1. Kenn,

        I’m not sure of his time in country but by any chance do you recall a FAC named Jim Tillotson? His call sign was Cutie 1-5.

  5. Hi Joe, my dad Hyun Ku Yun went to Vietnam to teach Tae Kwon Do with the Tiger Division. He was a grandmaster and said he was stationed in Saigon and Qui Nuon. Did you know him? If so, do you have any memories of him that you could share with me?

    1. Lisa, I was never in or near Saigon, but I was near Qui Nhon and traveled there as part of my duty throughout my year of service in Vietnam. I am sorry to say I did not know your father, but I did meet many South Korean soldiers and they were all very good men, as I am sure your Dad was.
      If you have photos of him during his time of service in Vietnam, I could post them in some Vietnam Veteran Facebook groups with an inquiry. Contact me through the contact page of this website, if you like.

      1. Hi Joe, thank you for your response. Unfortunately, we don’t have any photos from Vietnam because they were destroyed in a house fire in Korea. I am looking forward to reading your book.

  6. Love the article Joe. I too went to the ROK camp to learn Tai Kwon Do when there with you although I wasn’t vey good. They kicked my butt. LOL

  7. Hi Joe!
    My dad was stationed with the Tiger Division (ROK) outside Phu Cat in 1968 with the US Army. When were you there? Id love to talk further and see if you knew him or have a way of finding others that may have known him during that time period. Thx!

  8. I made an ambulance run to that ROK position late one night. A SP jeep led the way, it was at least a mile from our wire. The ROK’s were all hunkered down in their fighting positions because of sniper fire. I followed my escort upwards through a trench to a small dugout bunker, barely lit with a little candle. The ROK officer that had come to the Dispensary looking for help, had described through gestures what I thought would be a gunshot wound to the head. Instead my patient had only suffered a small forehead laceration when he had dove for cover. Easily patched up, I then ran a gauntlet of appreciative ROK’s, grateful we had made the trip. My driver, waiting anxiously for my return, informed me our escort had left. Unarmed, with snipers reported in the area, we cautiously but quickly made our way back to the safety of our perimeter. Medic, Phu Cat AB, 70-71′

  9. I was assigned to the gun platoon of 129th AHC (slicks were callsign Bulldogs and guns callsign Cobras [Bravo and later, Charlie and Mike Model UH-1 gunships]) at Lane AHP, south of Phu Cat and NW of Qui Nhon. Lane shared a perimeter wire with the Tiger Division HQ while the 129th’s mission was Capital ROK/Tiger Division support. Our AHC did stellar work with the ROK’s who were some of the finest infantry in VietNam. regards, (Cobra) Alemaster

    1. Thanks for sharing with us Alemaster, those ROK’s were damn fine troops. And you guys did a pretty good job yourselves.

  10. In 1967 we did convoys daily between Qui Nhon and Pleiku with tractors pulling tankers full of 5,000 gals. of jet fuel. About a 200 mile round trip. We would pass a lot of infantry humping along the roads and they use to refer to us as Zippos Trucks, like the Zippos Lighters and it stuck with most of us. I broke down and there was some mix-up and no one came back for me and had to spend the night somewhere around the An-Khe Pass just me. I can’t recall what happen that night but the next morning I woke up in a Tiger Division Soilders Camp with just pants on. I was beat up badly. I was there for a week or so before my company came and got me. My M14 and everything else were gone. The only thing I learned that Korean Soilders found me in the bush far off the road and the only thing I had on was pants. Truck and tanker were gone. There is more to the story but to long. They apparently saved me. There are so many holes I just can’t remember them. Here is the outrages thing about this, there is no record that this happen to me. WHY no record? I think I know why no record!

      1. Joe VA sent me to a VA head doctor and he has help me pull somethings out I didn’t even know was there. It appears that the VC took me and took me into the bush but apparently didn’t kill me because they were scared off by the Korean Soilders. Apparently they had enough time to take everything from me but my pants. That’s all I have right now to try and explain what happen to me that night. Yes I am very glad they saved my butt.

      2. Joe, thanks for your efforts in preserving this rare record.
        I never expected any sign of recognition.
        Someday I hope to visit MacArthur Park in Seoul, to pay homage to the ROK there, and attest to our brotherhood.

  11. Are there any resources about The experience of black soldiers in the Vietnam war who were posted to Korea? Is there a sign visors group?
    Any info about these soldiers specially suffering from the effects would be appreciated.

    1. Jill, I’m not sure I understand your inquiry. I am guessing you are referring to black soldiers posted to Korea DURING the Vietnam War. And you are asking about a survivor’s group. I was stationed in Vietnam during the Vietnam War, so I’m not totally familiar with anything that went on in Korea during that time.
      Suggest you search for some Korean War Facebook groups, for that information. You may also contact your local American Legion or VFW with your inquiry.

      1. I was with the ROK Marine Corps, Blue Dragon Brigade, Ranger Co. Hoi An, Vietnam, from May 1968 to April 1970. I was with Sub Unit,1st. ANGLICO Marine Corp. two man team, Running air support, medically, evacuation, and resupply. We were at blocking force for the marines operating in the Dodge city area, south of GaNoi Island. I just began writing my memoirs last year. I have two years of battle stories from all of the operations that I was on. One being “Operation Pipestone Canyon.” And another, the last beach landing in Vietnam “Operation Defiant Stand” on Barrier Island. One thing that sticks in my memory was riding a ROK convoy into DaNang, watching the top of Freedom Hill ammo, dump, blowing off as a magazine of 2,000 pound bombs exploded. Then the thousands of Vietnamese refugees from “Dog Patch” came out like a wall of human flesh and nothing could move. To this day I avoid crowds!

  12. Here is a ROK Army story from a different angle…the Korea DMZ. I was in a towed 105mm howitzer battalion that deployed at the DMZ in 1973. The Tiger and White Horse Divisions returned to Korea from Vietnam in March 1973, and gradually their sub-units re-deployed along the DMZ, next to my unit which cooperated with them. I was a medical corpsman and accompanied the ROKs on some of their “hunter-killer” patrols within the DMZ, observing their tactics while searching for North Korean infiltrators…QUITE IMPRESSIVE!

  13. Hi Joe,
    Many of us were stationed at Phu Cat Air Base during the war and were very appreciative of all the ROKS did to keep our base secure. Do you know if there is a FB page or site where we can just tell them thanks for all they did. I have found nothing over the years and have never had the pleasure to meet a former soldier.

  14. My last tour in the army I ran into an Army doctor and he told me about his duty in Nam. He told me he assigned to a ROK unit. I mentioned he must of been safe being assigned to the ROK Army and he said yes…I was very safe.

  15. I did three tours in ROK—two long, one short (5yrs total) became proficient in Tae Keon Do & Tang So Do. Been married to a Korean for 42yrs. One thing that was interesting was all Korean males did time in the military and exemptions were rare.

  16. Enjoyed reading the stories …. I was at Phu Tai with the 173rd … It was a very small compound and we shared perimeter wire with both an Engineer and Transport company … there was a ROK base to the north-east of us (I think, no one remembers our base or the exact location ).. Anyway I was on guard duty on a tower one night – 1971 I believe when I saw the ROK’s get hit with Mortars and small arms fire … front row seat, I can never find any info or reports about that night except for the fact that I met a TOC specialist stationed on our base (met him thru facebook)… chatting on the phone a month ago… he says “were you there the night the ROK’s got attacked” – confirmation at last!! 🙂 I’m still searching for fellow 173rd’s who were there at that time. Does Anyone know where that ROK base might have been or the name of it? Phu Cat would have been too far away for me to have seen it…I’m on facebook … Take Care.

    1. I think it was the ROK Tiger base outside Qui Nhon. I was stationed with 84th Engineers C company beside ROK base. Drove fuel truck to construction sites and gave them rides back to base. Nice guys but would not want to get on the wrong side of them according to the reminders they would leave for VC, body prop up with with thinking part beside them next to road. What ever you hear about them being dedicated, yes it’s true!

  17. My father US Army Retired Colonel Glenn Beil recently passed away. He served in Vietnam from Nov 68- Oct 69 as a Major and always spoke highly of serving alongside the Tiger Division soldiers. His main locations were at Qui Nhon and Nha Trang. If anyone has any memories please comment. I was also curious if the Tiger Division had a motto?

    1. Sorry for your loss Brian. I am not aware of any ROK motto, the unit I was involved with being very small, perhaps other readers will comment on it.

  18. I was a young Marine in 7th Comm Bn, 1st Marine Division. and a part of a three man Radio Relay Team from Thanksgiving Day 1966 till 12 March 1967 assigned to maintain radio telephone communications at the 2nd ROK Brigade north of Quang Ngai. I am one of the most appreciative of those of us who made it out of that place. I was honored to serve with some of the finest fighters ever sent into the teeth of the enemy. The ROKs taught me a lot of life lessons when I was 19 years old. As an elderly person I’ve learn you can’t really choose who will be your friends… they just are. I count those men, both alive and past, as my deep, deep friends.

  19. I wish I knew of any ROK Tigers that are now living in this country. I would love to meet them. I was at camp Thunderbolt

  20. Truly enjoyed this life-story of yours, Joe. Flash-back to 1968 at Phu Bai – I befriended a one Captain Lee, ROK, while stationed there. I happened to stop by his hootch one day and saw him playing, what I soon found it, a game called “Go” (Baduk in Korean). Sort of a chess/strategy game. Before I knew it, I was invited in to watch. This soon turned out to be a learning experience that lasted almost until I left Phu Bai in ’69. In turn, I would teach him various phrases of English and he in Korean. It wasn’t too long after this first encounter when he flat out asked me to join him in Tae Kwon Do (TKD) practice at the MACV compound the next day. I showed up as soon as my duty was finished for the day. The small work out area (Dojang) was a corner of the compound, rock solid hard concrete floors, a hanging duffle bag filled with sand for punching/kicking practice….and me…without any uniform (dobak) to wear. Some of the students soon found me one to wear that was about 4 sizes too small. However, my skinny 127 lb. frame took to it just fine. I should go on to say that I was the ONLY non-Asian student in class. All young (weren’t we all?) Vietnamese ARVN, Captain Lee and another Vietnamese officer (Captain) of which I cannot remember his name. Training was tough as nails, no talking back of goofing off in class. Hard core training, being thrown to the floor many times over, struck everywhere with no protective gear, bruises all over me…..but I loved every moment of training. I, too, was razzed by my company “Commander” for training with them. That didn’t stop me, of course. I just ignored all the BS from him (and others).

    My time to leave Phu Bai came around, I said my goodbyes, but sadly Captain Lee’s contact information was lost by me over the years. All pictures, unfortunately, were destroyed in a basement flood many years ago. But my love of TKD, along with TSD and other Arts never waned. I continued my study once back in the states. Taiji (Tai Chi is my current study and has been so for over 40 years now.)

  21. Joe I was stationed with the 48th AHC in support of the 9 ROK White Horse Division in 1968 – 1970 located in Ninh Hoa.
