In '69,during BCT,the Army wanted me to go to OCS.I turned it down largely because of the belief that the average life span of a Second Lieutenant in Vietnam was about two days.
Of course,things certainly might have changed since then.
In 1967 I turned down a cross-service commission as an Army 2nd Lt to fly rotary wings in Viet Nam (I was an Air Force Sgt). Average life span of a 'copter pilot was 10 missions. So they made me a gunner on a B52 instead.
Of course,things certainly might have changed since then.
I'm pretty sure the life expectancy of a Second Lieutenant in Vietnam is longer than two days now...
