Your numbers are in fact wrong.
Profile of US Servicemen (1941-1945)
38.8% (6,332,000) of U.S. servicemen and all servicewomen were volunteers
61.2% (11,535,000) were draftees
Average duration of service: 33 months
Overseas service: 73% served overseas, with an average of 16 months abroad
Combat survivability (out of 1,000): 8.6 were killed in action, 3 died from other causes, and 17.7 received non-fatal combat wounds
Non-combat jobs: 38.8% of enlisted personnel had rear echelon assignments—administrative, support, or manual labor.
Average base pay: enlisted—$71.33 per month; officer—$203.50 per month
No they aren’t, read my post.
Yours are the numbers for the entire military and the Coast Guard, not the Army, which was 93% draftee.
