Totally subjective rating of backpacks in BRM5 based on personal experience
1. LBT-1476A
35 slots, 1.2kg. Offers a pretty flexible and relatively lightweight loadout while balancing distribution of ammo and meds evenly. Can carry well over enough supplies to solo small compounds and enough to make decent progress in completing objectives in larger locations like Fort Ronograd or Naval on your own. Most diverse color options out of any other bag.
2. TSSI TACOPS M-9 Assault Medical Bag
28 slots, 500g. Good carrying capacity for its weight. Has usable MOLLE, but only enough space for tourniquets. Only bag with UCP.
3. SSO ATAKA 2
56 slots, 2.8kg. Dirt-cheap, lets you carry a lot. Only real downside is the weight. Pretty standard colorways, except for EMR and ATACS-AU.
4. Backpanels
24 slots, 450g. For LARP purposes only. They look cool in their own right but are outshined by dedicated standalone bags in terms of inv slots. Not sustainable for long-term deployment and you'll run out of ammo fast if you break stealth.
5. 6B46 "Adler" Three-Day Patrol Backpack
36 slots, 1.7kg. It's 500 grams heavier than the 1476A (of which it is almost visually identical to) and offers nothing to compensate for the extra weight besides 1 extra inv slot and has less camo options. Standard colorways, in addition to EMR.
6. LBT-8005A
24 slots, 570g. Barely distinguishable as MIL-SPEC, you might as well be rocking a JanSport. Black multicam option is split between MAS grey and mcam, which makes it look patchwork and ugly. Has potential to carry nalgene bottles in the side pockets, but atm lacks functionality in-game to do so.
