I'm going to BCT in a month and straight through to AIT for a combat MOS, was just wondering about the stance on personal equipment (tac vests, camelbacks, etc) while in a combat zone.
It varies, unit to unit and depending on conditions. Your unit may sya "everybody wears this gear, this way" or they may say "wear whatever you want." I've been in units where we were literally allowed to buy those old 80's "moon boots" (in 1984-85) and spray paint them black and wear them in the field (we were artillery, so it was mainly about keeping your feet warm while sitting still). Other units wouldn't even approve the German army boots that nearly every soldier in Germany had.
