I'd go with 3 liters of water, a plate carrier, light helmet, pvs-14s, a good knife, my walkaround aid bag, a 1911 in a chest rig with 4 mags total, and my Moisin-Nagant M44 with one hundred rounds and a comfy sling, an ACOG, and some sort of PEQ. Since I won't be alone, all the other guys can carry the heavy crap. All I really need to shoot at is what they miss, so why carry something that isn't fun?
In all honesty, I'd rather have had my Moisin in Hawijah than my M4. I really think I would have shot better when I needed it if I'd been forced by the rifle to aim.
