Ammo Box Glitch

The ammo box glitch is when you have 2 or more of the same type of weapon (with or with out the same modifications )in fireteam. For example, say you have 2 M4A1s and then you start using the one in your backpack slot. You soon run out of ammo so you then search for ammo. When you reach a yellow ammo box, you run over it and you still dont have any ammo in the M4A1 that you are using. In fact, the ammo from the yellow box went to the M4A1 in you primary slot. You can still run over as many yellow boxes as you want, but you will only take them all, get no ammo, and leave none for your allies. If you take a red box, they both get refilled with ammo.
