M-1965 field jacket
The M-1965 field jacket, officially Coat, Cold Weather, Field (also known as M65, M-65 field jacket, and Coat, Cold Weather, Man's Field), named for the year it was introduced, was a popular military field jacket which for decades was issued to supplement fatigues and BDUs for colder or wetter conditions. The M65 field jacket was widely fielded and used by the United States' forces during the Vietnam War, in which the jacket became useful for troops serving in the Central Highlands of South Vietnam due to its wind and rain resistance, especially in the monsoon season and after.
