I noticed that the new specializations are tied to squad roles. While it's a move in the right direction, players currently can hot swap between open squads to gain the specialization boost from that squad at any given time.

Instead, I think specializations should be tied to what chest rig you are wearing.

Say, you have the standard ALICE chest rig, so you reload the M16 rifles a little faster than usual, or you have the Automatic Rifleman rig, so you reload LMGs slightly faster. (Do note that the US does not have a Medic chest rig as of this moment)

Additionally, chest rigs could reduce the inventory mass of items related to their role; for example, the Medic chest rigs could reduce the inventory mass of bandages, torniquets, and even saline.

Technically something like this is already done with shirts, rigs, and flashlights. Placing a flashlight on the US or Soviet chest rigs or shirts clips the light to them without taking up pocket space. The dream is there!
