Answer 1

Actually, there have been many US presidents who have served as military officers and therefore, "commanded troops" during war time (24) although several (6) had non combat service only. Additionally, there were a couple of presidents who served as junior enlisted members only (i.e., privates) and therefore, did not "command troops.":
