Yes it is a roll of the dice, and hundreds of thousands of soldiers like myself wound up "over there" but never saw combat.
And plenty of others who thought they had a good deal going, then events came along that proved otherwise. The occupation-duty troops in Japan used to form Task Force Smith in the early days of the Korean War come to mind.
I never asked to go most of the places I was sent to, I just went and did my job as best I could. I've got no problem with others who did the same, whether hard times in combat came their way or not. Maybe if I hung around those such more, their good luck would rub off on me....
