Cold War Files: All Units: Events: Troop Levels Reach 389,000

By year's end, U.S. troop levels reach 389,000 with 5008 combat deaths and 30,093 wounded. Over half of the American causalities are caused by snipers and small-arms fire during Viet Cong ambushes, along with handmade booby traps and mines planted everywhere in the countryside by Viet Cong. American Allies fighting in Vietnam include 45,000 soldiers from South Korea and 7000 Australians. An estimated 89,000 soldiers from North Vietnam infiltrated the South via the Ho Chi Minh trail in 1966.
