Length of involvement: By the time the last Filipino unit in Korea was withdrawn; the Republic of the Philippines had already started giving some rudimentary assistance to South Vietnam. In 1964, medical units were sent to Vietnam. Despite this dictator Ferdinand Marcos was at first reluctant to send troops. A whole host of US diplomats including Vice-President Hubert Humphrey were sent to finally convince him.  In 1966, the first combat units were deployed but; by 1970 they had been withdrawn again leaving the medical units alone.

The Force:  The "Philippine Civic Action Group" at it's peak in 1968 commanded 1,576 soldiers. The force was mainly a combat Engineering Battalion. Consisting of two "Civic Action Teams." and psychological warfare team. In the Philippines psyche war had proved quite effective against the Huks. A year latter only a token force of 139 remained. All military forces were withdrawn on Oct. 4, 1969.

Weaponry:  .A picture of a Filipino patrol shows the group armed with M16s and wearing a soft hat. Originally the Battalion was given M14s and M60s by the US.
        This was out of line with the standard Filipino weaponry of the time which include M1 Carbines and M1 Garands. They had the heaviest armed squads in South East Asia: 2 BARs, 5 Garands, and two Garand GLs.   The Security force also used M113s for patrols.

Training: When considering the Filipino soldier one must remember two things; 1) The jungles of the Philippines were not all that unlike the ones found in Vietnam. 2) The Philippine military had much experience fighting it's own anti-insurgency campaign against the Huks.

Interaction With Civilians/Others:  No information available.

Actions: Based in the Corps II Zone the Filipino HQ was at Tay Ninh. From here they conducted operations not merely in Tay Ninh but rather in many provinces: Tgy Ninh, Hau Ngia, Bing Dong, and Din Toung. The unpopularity of the war at home forced a general withdraw. However; by allowing the US forces use of Subic Bay  and Clark Airforces bases the Philippines perhaps made it's greatest contribution.

Vet Issues: Interestingly enough former Philippine president Fidel Ramos served in this war as well as the Philippine forces in Korea.

**Many American films on the Vietnam War are filmed in the Philippines.
 
 

Length of involvement: The country has always been a bastion of Anti-communism. In 1954, the ROK still pulling itself together after it's long war offered to fight with the French in Indochina. The French refused. A mere ten years later The Republic of Korea(ROK) agreed to commit troops to another Indochina war. The ROKs was firmly entrenched in CTZ II by late 1965. The Koreans fought on until 1973.

The South Korean Force: Was the 3rd largest allied force in Vietnam consisting of 2 full infantry divisions and a Marine brigade for a grand total of 48,000 fighting men. In 1969, more ROKs were committed in South Vietnam than North Vietnamese. In addition 272,000 support personnel were involved in the war. As far as I know the Marine brigade numbered 4,000 and was the first combat unit deployed in Vietnam by the Republic of Korea. By 1972 they outnumbered the Americans present in Vietnam. South Korean units had a rather colorful nickname.
2nd Marine Brigade: Blue Dragon
Capitol Division: Tiger
9th Division: White Horse

Weaponry: One photograph I've seen of ROK Marines shows some of them carrying M16s and others carrying what looks like either M1 carbines or M2's . M1 Garands were also used. Note the bullet proof vests, below.
 

Elite: While all their units were certainly above par, The S. Korean's 48th Marine brigade was superb. One Korean newspaper article also said paratroopers were sent  to the war,  I don't know anything about this.

Interaction With Civilians/Others: Here are a few quotes:
"Our Platoon would often swap trade with the Australians....No-one swapped with the Koreans though,"
                                  -An American soldier complaining about C-Rations
"South Korea and the Philippines-played the part of corporate mercenaries."
        Introduction to Australia's Vietnam
 "The Korean's know how to handle the  Vietnamese."
                                Credited to an Australian Battalion Commander.
"Contact with the Koreans is to be avoided at all costs unless victory is 100 percent certain"
                                Captured VC documents

Actions: The South Koreans operated out of CTZ II. In 1966 a joint ROK-US action took named Operation Masher-White Wing.  Unlike the US They favored multiple detailed sweeps and on the spot interrogations of  suspected VC. They tried to bypass interpreters and learn at least crude Vietnamese. They were rarely given the luxury of Chopper assaults and as a result their limited area of operations was 100% secured. Their units grudgingly withdrew starting with the Blue Dragon which left in February of 1972. On March 6th, 1973 the remaining units left being the last allied units to do so
 

Vet Issues: South Korea is beginning to come to terms with some of the less honorable  war time actions of their soldiers. However, a bigger issue lurks as a result of a secret deal with the LBJ government the ROK vets are entitled as much as 1 billion dollars due to political agreements and judicial rulings. When the Agent Orange lawsuit was settled in the early 1990s money was paid to many non-Asian countries involved the US, Australia, New Zealand and even Canada. According to Seoul 17,800 veterans show the effects of Agent Orange. Some 6,000 Koreans did receive 10.1 million dollars in death and disability compensation from the US.

Length of involvement: 1962-1972, The Last New Zealand unit was rotated home in December of 1971.

The ANZAC Force: The Australians and New Zealanders contributed 8,300 soldiers which is included in a grand total of 46, 852 personnel and advisors. Australian SAS, infantry, destroyers, bombers, artillery and other units served in Vietnam. The Draft began in Australia in 1964. As here in the US many dodged it and went to court in order to avoid service. Not since WWI had a war's conscription been so controversial in Australia. A National Serviceman (Draftee) Served 12 months and formed no more than 50% of any unit. Regulars were forced to have a 2-year gap between tours. In addition volunteers were common: Australian officers realized Vietnam experience was needed for a climb to the top. Despite draft-dodgers most NS men were in agreement with the with the call-up. Beer..excuse me Fosters was rationed at 2 cans a day. Despite this lax policy court martials often involved excess drinking.
    The New Zealand forces on the other hand were 100% volunteer. Like the Australians they had Jungle Warfare training in Singapore and Malaysia.  The Kiwi units included 161st Battery, Royal New Zealand Artillery. Two NZ Infantry Companies Victor 1 Company and Whiskey were deployed as well as a New Zealand SAS squadron.
 

Weaponry: The Australians choose AR-15s and M60s. However, exotic weapons like the Owen SMG and the Heckler & Koch G3  were also carried. Some Centurion tanks were also deployed and they used M113s dor transportation.

Training: Was just intensive; 4 weeks Jungle Warfare Training for infantry and 3 weeks for individuals assigned other units, In addition some units spent a good year drilling for a Vietnam tour. This intense training speaks volumes for their success.

Interaction With Civilians/Others: The VC was firmly entrenched in the villages of Phoc Tuy and the Australians tried to build up a good relationship and win them over. Forced relocation of some villagers early on made this a losing battle. The Australian and NZ soldier gained a reputation as hating everybody: they hated South Vietnamese, Local Chinese and even Americans. It is important to note however they did follow the instructions and tips sent to them from Saigon. One US general had a high opinion of them; "Aussie troops were so good we ought to make better use of them. " Both Americans grunts and Australians soldiers thought the discipline in the other organization was extreme and overdone. One US Marine felt that their allies did a whole lot of sneaking around and needed to try actually fighting their VC counterpart. In sharp contrast a VC document stated "Watch out for the Australians. They don't attack the way they should, but hit you on your flank or rear without warning."

Elites: The average "Aussie" or "Kiwi" troops were in general a step above than there average "yankee" counterparts mostly due to the former’s intense training and the intense feeling of citzen-soldier among the Americans. However; even the Australians and New Zealanders had their elite, the Special Air Service(SAS). Supposedly 1 SAS was killed for every 300-400 enemy, Compare that to 1 for 25 on some of the better trained ARVN units. Three Australian SAS squadrons rotated in and out of Vietnam from 1966-1971. Ironically this was the last known use of these forces.

Combat: In 1962, a 30-man advisors unit lead by Brigadier Ted Serong was sent to Vietnam. This unit called simply "The Team" was also the last Australian unit to leave. Early on the first Australians were attached to the 173rd Airborne brigade and participated in several operations. Australian combat actions centered around the Phoc Tuy Province from May 1966 to November 1972. It was essentially a low-level intensity combat area controlled by an Australian Task Force. The Australians met not only VC attacks but also a very pro-VC population in their counter-insurgency campaign. The most significant battle happened near Nui Dat on August 18th, 1966. The "Battle of Long Tan" as it was to become known involved a surrounded company of Australians fighting a superior force of VC in the midst of a rubber plantation! The Australian forces held together and pulled off a victory of Rorke's Drift scale. The task force also initiated a version of the "McNamara Line" the 12-mile minefield from Dat Do-Phouc Hai. It was an utter failure, VC forces lifted whole sections and used the captured mines against the Australians.

Casualties: As the years went on more Aussies died serving at home than in Vietnam. The final death toll was surprisingly low 494 killed casualties and 2,398 wounded with no POWs. This includes the Royal Australian Navy who lost 8 men and a further 46 wounded. The New Zealanders suffered 31 KIA and no POWS.

The Force:  40,000 to 30,000 Canadians from throughout Canada are estimated to have gone south to have fought with the US in Vietnam. Officially the number is 5,000 because many Canadians used a US address. Canadians served for adventure, US Citizenship, and for economic reasons.  Parallels can be drawn to the French Foreign Legion or the Americans who joined the Canadian Military before the US entered WWII.
       The war was unpopular in the Canadian government. However, with the possible exception of Fiji the Canadians are the most active peacekeepers in the UN.  They agreed along with Indonesia, Poland, and Hungry to monitor the acceptance of the ceasefire. The Peacekeepers were soon withdrawn when violations were discovered.

Interactions With Others: The Canadians were called "wrongways" by American soldiers. After all some Americans were trying to flee to Canada to avoid Vietnam not the opposite.
"the fate of Canada was tied to the fate of it's closest ally...We believed in Helping the US."-Canadian Vietnam Vet.

Casualties: 106 KIA and 7 MIA. However veteran groups believe the number of KIA is between 300-400.

Vet Issues: In 1994, for the first time vets marched in the Canadian Armistice day parade and placed a wreath at the memorial. A memorial has been erected in Quebec. The Vets also received a settlement from the Agent Orange lawsuit.
 
 

ROC: Taiwan needless to say is strong anti-communist state. So when Chiang Kai-shek offered troops to fight in Vietnam, as in Korea the State Departament said no. Only 31 soldiers were committed in order not to bring the PRC into the war. Newspapers urged Chinese in Saigon and elsewhere to enlist in the ARVN. A larger ROC presence may have brought China fully into the war, in addition the Chinese have always been hated by the Vietnamese as invaders.
Malaysia: Contributed advisors initially and as the exchange of delegations continued, more was promised. Despite the war with Indonesia; 2,000 RVN officers were sent to Maylasia and trained in counter-insurgency warfare.
Japan: By 1967, 90 technical advisors were in country helping build electrical power plants and engineering roads.
Italy: Sent a team of surgeons in addition to other supplies
Spain: Sources differ some maintain that the 13-man force was medical others say the group was of military origin.
Iran: 1,000 tons of Petroleum products and a medical team were donated to the RVN.
Britian: British personnel trained US Combat tracker teams in Malaysia. A few British SAS are rumored to have joined their Aussie counterparts to serve. Also Interestingly a high number of new British emigrants to Australia also served in Vietnam. In 1975 the H.M.S Mermaid, A Royal Navy Frigate, was made ready to evacuate British nationals from Siagon, but; the need did not arise. Overall, very supportive.
