M45 shotgun

The M45 TS is a shotgun used by the United Nations Space Command. It will be featured in Halo: Reach.

Design Details
Much like any other shotgun, the M45 TS is a special-purpose weapon used in any situation where the range of engagement is limited, over-penetration is not desirable, but maximum stopping power is required.

Trivia

 * The M45 TS will presumably be more powerful than the M90 Close Assault Weapon System in Halo 3 since Bungie has stated in a Game Informer interview that the rounds will now be packed closer when fired and the range has been improved as well. It is perhaps as powerful as the Halo: Combat Evolved version was, although it wasn't mentioned whether the ammo capacity has changed from the Halo 3 version.
