To go along with my esteemed Engineer colleague, after the first few patrols, ammo issue and mag recharging became much less organized and more of a social circle than anything. We never had any match ammo, but a variety of everything else to load.
We also carried a dump bag as well, and I was always paranoid about leaving my mags laying around. I didn't want some little Afghani kid to pick one up and then get killed for it by the Taliban.
