At least you guys have Molly Vests. Us oldies had to try and survive with web belt and suspenders, which could never carry enough water or ammo for a day's work. We ended up usually stuffing cargo pockets with extra rounds, etc. Net result: carrying 70-80 pounds of crap from the hips down, instead of distributing the weight around the torso.

My calves ache, just remembering that. :)
