A kit or backpack is the in-game representation of a player's class, and is used to carry that player's weapons and devices. An icon (and occasionally the kit's design) helps players identify the kit's class from afar. Upon being killed, the player drops their kit (after a short delay in some games), which can be picked up by another player and swapped for his own.
Using another player's kit provides immediate access to the player's selected weapons and gadgets. Any deployed devices will still function for the original owner, though the player can resupply and deploy replacements (destroying the originals in the process).
- In games like Battlefield: Bad Company and Battlefield 1943, a kit appears as a duffel bag. In games like Battlefield: Bad Company 2 and Battlefield 3, a kit appears as the player's primary weapon.
