List of UNSC crates

Scattered throughout multiplayer and campaign levels on Halo 2 and Halo 3 are UNSC crates, or large boxes, that contain supplies for ground based Marine forces. The contents of crates can be identified by their labels, and range from portable generators to armored boots. Although their only actual use in the game is cover from enemy fire, they do reveal a bit about the UNSC military. =Halo 2=

Crates
There is a range of different types of crates. This section contains information on all of them, ranging from smallest to largest. Kits are small crates that appear to be carried by Marine ground forces. Barrels contain liquid supplies. Small crates carry equipment used by ground troops, and large crates contain large pieces of equipment for use at fixed positions.

Rescue
The first crate can be found only once or twice in the game; it appears to be a small medical kit Marine medics would use to treat the wounded. It has the word "Rescue" along with the international medical symbol. It is likely able to be found in various campaign levels at Marine positions, but it can only be found once in multiplayer on the map Foundation.

Nerve Gas
This container can be found in brute encampment inside armory, it is placed under another crate so it is pretty difficult to find. The crate has been spotted on the multiplayer map Foundation too. Perhaps it is with a bit of dry humor that Bungie placed this small crate right next to a medical kit within the same room.
