I have never served but the important men in my life have:
Dad: Enlisted, Navy; WWII. Bombardier in the Pacific in a makeshift civilian aircraft. Shot down three times; spent last six months of war in a psych hospital for "battle fatigue."
First Husband: Drafted, Army, 101st Airborne; Viet Nam. Ground pounder on point for the incursion of Cambodia. Untreated PTSD sent me running from that marriage.
Current Husband: Volunteered for the Navy on a bet with drunken buddies and was the only one accepted; Electronics Engineer E-5, but two or three Captain's mast's for being insubordinant with his immediate officer. Honorable Discharge. Claims to secondary fame: His ship picked up John Glenn (USS Noah); he calculated and strung a communication line for sending an SOS after his ship's upper deck was taken out by a hurricane; and he decoded and delivered the CoC's (JFK) message to his captain to meet the Soviet fleet and prevent their arrival to Cuba.
Overall, not bad for a nonconformist sob.
