Up until I got out last fall, my LBV was configured to hold up to a total of 24 x 30 round mags, plus one in my weapon. I had the 6 on the chest, plus 4 x 3 mag pouches on my belt, and another 2 mag pouches attached to my buttpack. Of course, more often than not, these pouches were occupied by map marker pens, camo sticks, 550 cord, spare batteries, and other assorted junk needed by a FO.
Chindo, welcome to THR. What group are you with?
