OK, here is my setup:
Line 1 gear:
Kimber TLE/RL with Surefire X200 in a low-ride holster strongside with xtra mags on the holster
Low-ride dual M4 mag pouch on weak side, all held up by a heavy duty riggers belt
Pockets stuffed with essentials, i.e. Energy bars, combat folder, gloves, etc.
Line 2 gear:
HSGI Woosatch with pouches to hold 8 M4 mags, 2 .45 mags, my Gemtech supressor, and a large utility pouch. In the UP, I have more food, a couple of knives, firestarter, paracord, multitool, etc.
I also keep a Camelback 3L in a TT hydration carrier on the rear of the plate carrier.
Line 3 gear:
I have an ALICE medium pack that I fill with MRE's, extra water, extra clothes, socks, boots. I also have a poncho, sniper veil and a cooking setup along with other stuff I can't remember.
If you set your geat up this way, it is much easier to keep it all organized and it allows you to fight & survive to the bitter end.
