Uncle Sam ain’t no woman but he sure can take your man
Uncle Sam ain’t no woman but he sure can take your man
He’s taking them in the daylight to go to Korea and fight
The people over there are messed up, they are many very rough
The people over there are messed up, they are many very rough
We have to go there and show ’em what it means to be real tough
So pray for me baby I’ll be thinkin’ of you night and day
So pray for me baby I’ll be thinkin’ of you day and night
And with the help of the Maker every day will be allright

Conscription in the United States (the draft) has been employed in all major conflicts including the American Revolution, Civil War, WWI, WWII,  Korean War and the Vietnam War.

America’s first peacetime draft began in 1940 through the Selective Training and Service Act. 

From 1940 until 1973, during both peacetime and periods of conflict, men were drafted to fill vacancies in the United States Armed Forces that could not be filled through voluntary means.
