I would like it if the Ammo pouch of Grenade pouch increased the AT gunners secondary ammo reserve, for things like th PIAT and Grb 39.
I would also like it if it could also work for rifle grenades.
No backpack=3 grenades
Small ammo pouch=4 grenades
Large ammo pouch=5-6 grenades
Could also work with grenade pouch, where instead an extra grenade in the slot, you could have two extra explosion ammo.
At least AT guns ammo can be replenished from ammo boxes.
Rifle granades getting more ammo from bags would be nice, they work best from high ground so running whole rifleman squad into position one by one sucks now.
