Using my modified MOLLE I belt system and the green lumbar pack I sewn up, I have made an overnight patrol, to 3 day patrol setup.
2x CMVS Triple ammo pouches
2x Canteen covers
2x Tactical Tailor Large Utility Pouches
2x Tactical Tailor Medium Utility/Canteen pouches
Knife sheath on belt portion
Pack setup 1
Pack set up 2
External pockets emptied except for AR-15 carbine (would be on my person)
Ammo, goes in CMVS Triple mag, water in canteen , metal cup both goes into canteen cover, food goes into Large Utility Pouch
other water bottle into other canteen cover, 10×10 Bushcraft USA tarp and bunch of paracord goes into other Large Utility Pouch. Medical kit goes into insert, whatever does not fit goes into the bottom of Medium utility pouch, then the plastic insert box goes on top. stakes, and fire starting kit with Esbit folding multifuel stove goes into other Medium utility pouch, some stakes would do double duty as canteen cup holder on the Esbit stove.
Hirsch-Weiss (White Stag) Goose Down mummy sleeping bag out of main bag, with clothes.
Left to Right; Poly-merino wool long john underpants, nylon long sleeve camo shirt, woodland BDU pants, wool socks, and extra underwear. The wool socks and the long johns are for when it gets colder, and I sleep in base layer in the sleeping bag, the other clothes are change for next day or two days on. Fleece pull over or COld Weather Parka with liner would be worn if colder weather, if not, then lash fleece pull over onto the bag, if dry weather is expected..if wet weather, parka or M65 jacket with fleece inside.
Basically this is an overnight system, and up to 3 days, if I pack extra socks and underwear as well.
