Long War added a lot of items for abilities that were previously only available as a perk, such as Battle Scanners.
The Jungle Scouts starting bonus from Brazil also increases this to 3 item slots for the early game armors (Tac Vest, Tac Armor, Kestrel Armor, Phalanx Armor and Aurora), but this bonus does not stack with the bonus from the Tactical Rigging Foundry project.
The Tactical Rigging Foundry project increases this to 3 slots. In Long War, all regular soldiers have 2 equipment slots from the start of the game.
