A lot of things are not hidden behind rank, and some, on the contrary, are closed for no reason.

1) RPG Backpacks - They're currently available immediately, starting at the Volunteer rank. But the RPG itself starts at the Partisan rank.

Maybe it should be moved beyond that rank to make it more logical and make the rank increase necessary.

2) M70 Backpack, Type 56 Chest Rig - Volunteer -> Partisan. If you want to carry more gear, earn it!

3) M70 Parka, M70 Trousers, TAZ 83 Pants, M70 Cap, Tsh-4 Helmet, Leather Gloves - Move up the Partisan rank. Want to dress up and use camouflage? Raise your rank!

4) Military Tent - only for Squad Leader or Partisan or higher

5) FMJ Sa-58 Mag, FMJ UK-59 Belt, another FMJ ammo - increase rank to Partisan

6) Sa-58 Tracer Mag - Increase the cost to 1-2 supplies. This will make players understand that this is a valuable weapon.

7) Sniper SVD Mag - increase rank to Partisan. Then it will make sense to take other supplies.

8) Ammo Box for Mortar Rounds - Decrease to Volunteer. Imagine a situation where one player is a Partisan or higher, and his assistant is a Volunteer, but wants to help him

9) PKM - please add for Captain rank. Right now they have ammo for it and machine gun nest with it ;)

10) NSV - Too powerful. Maybe increase rank to Captain or remove it?

11) SPP Scope for NSV - Too powerful for FIA

12) Shopping List - Maybe leave it only in players' inventories so it can't be found through the arsenal?

13) B12 Binoculars - Maybe you should remove it from the arsenal altogether and leave only the USSR?
