The gradual U.S. withdrawal from the conflict in Southeast Asia is reflected in reduced annual casualty figures. The number of Americans killed in action dropped to 1,386 from the previous year total of 4,204. South Vietnam losses for the year totalled 21,500 men, while the combined Viet Cong and North Vietnamese total was estimated at 97,000 killed in action.
After 10 years of U.S. involvement in the Vietnam War, a total of 45,627 American soldiers had been killed. The U.S. troop levels, which started the year at 280,000, were down to 159,000. This troop reduction was a direct result of the shifting American goal for the Vietnam War—no longer attempting a military victory, the U.S. was trying to gracefully extricate itself from the situation by transferring responsibility for the war to the South Vietnamese.
