Holy crap! Which 5 theaters if you don’t mind me asking?I been in 5 different combat theaters, wounded twice and never worn body armor plates. I have gladly given up those plates for weigh reduction. It allowed me to carry more ammo. We didn’t wear helmets either, we wore boonies. A lot of what Bypass has said is true. Learn to fight smarter, know your egress points, shoot and move.
JMTC.......good luck
