I canny two different types of bags other than my actual gear bag. One is a Voodoo Tactical 2 day assault pack that has everything in it from protein bars and extra water, extra fleece gloves and hat, couple of blood draw kits, first aid kid, bino's, matches and a lighter, some spare pistol ammo, extra cleaning kit for pistol and rifle, ect.........
My main BOB for patrol is this
U.S. Peacekeeper with 30 round mags. In side I have an extra small flashlight in one side pouch and an extra pistol mag in the other, in the two main compartments are my first aid kit. I put it together from Larue Tactical.
First Aid Kit with
Celox Gauze, and
Celox Applicator. I'll be getting a couple more Isreali Bandages of Amazon soon enough. It's a simple down and dirty kit. As far as ammo goes, I have a 30 round mag in the weapon and a 20 rounder on my person,
Integrated Mag Pouch. That gives me a total of 170 rounds of ammo.
