Good idea on the multiple setups. I'm going to get an assault kit ready when I get my M4 upper here for my AR15. I'll probably get a differnet day pack and use my LCE set up. Its got mag pouches for 6x30rnd mags, the Butt Pack for some energy food and other accessories, 2 1qt. canteens, I'd probably lash the Yard Guard to it, and I'd carry my 1911 in a shoulder holster underneath of it. I'll probably get an assault vest w/ pockets for the other odds and ends too!
