Some military fieldkit wloud be pretty intresting, but i mean they dont perform miracles in the hands of an amature( nither should bloodbags). And the problem with the space in your pack? Come on, all the shit you try to get in there are as big as they are, they dont shrink because u want em to. You have a limit to how much u can carry, at least i have. You may have to sacrefice your precius 2nd primary rifel but its a crule world and you are trying to survive. When i where in the army as a ranger my backpack wight about 60kg but you dont go around running and crouching with that. Sop ( standard operation procidure): you got to survive with whatever shit u got on your body, on the ground, what u can scavange or kill for. The world will fight you, fight back and win Ps: wrote this on my iphone so sorry for the gramatics :p
