When you join up and go to a combat zone are you allowed to get sidearms sent to you from the states. The reason I ask is after I graduate im joining up and am going to try to be a M1A1 crewman, LAV crewman, or AAV crewman, and would like a sidearm in the closed in space I would be fighting in just in case. I understand that it is rare for a marine or any soldier to use their sidearm but it is a just in case type thing for me. and if I did have to use my sidearm I would prefer my father send me a .45 from home then use the 9mm. That is why I ask.
