Army Issue

Army Issue
You can change your weapon officers in the army?

if the army gives him a weapon (gun) and that is, let's say a 9mm, and that's the standard pistol for soldiers to carry, you can buy your own, say .45 and 9mm replace? Also when you get a rifle can make modifications to them (m4) to suit your needs or simply because you want?

You can not bring their own weapons to use in combat for a variety of reasons not to get too deep. You must use the weapons issue, but you can add your own equipment if desired cool guy. For example, I have a site EOTech holographic private property in my issued M4. You can not do no permanent modification to a weapon. I've heard of some people trying to make personal arrangements to bring in arms abroad, but have never actually seen fix. In all honesty, the M4 carbine is a great and in fact no one uses a gun around here anyway, except to carry around the base because it is easier to drag around a rifle.
