The Resupply Canister is a United Nations Space Command rearmament capsule. It is a long, oblong capsule with a length of 2.76 meters (9.06 feet) painted in olive green drab. In the interior is stiff blue foam that encapsulates a firearm, typically an M7/Caseless Submachine Gun, BR55 Battle Rifle, M90 Shotgun, SRS99C-S2 AM, or M19 Rocket Launcher. Pelican dropships may carry six Resupply Canisters on their tail assemblies and eject them in sequence, allowing the capsules to air-drop to the ground and implant themselves firmly into the ground. Upon impact, panels on the upper surfaces of the capsule pop off, revealing a partial profile of the weapon within.

Resupply Canisters are frequently used to rearm UNSC ground units in hazardous combat situations. They were used extensively during the Human-Elite offensive on the Ark and also appear frequently abandoned in Crow's Nest. They also appear by default on the muliplayer level High Ground and on Valhalla, having been dropped by Victor 398 before crash landing.

There are at least two types of Resupply Canisters: The Resupply Canister Type-B Capsule, and the Resupply Canister Type-C Capsule. The Type-B Capsule was used in Halo 2, and the Type-C Capsule was used in Halo 3. There is probably also a Type-A Capsule, but it hasn't been seen in action.
