Loadout

Loadouts are classes that a player picks at both the beginning of a multiplayer match and during respawn in Halo: Reach.

Details
When a game begins the player is given the option of choosing a particular loadout. Loadouts are gametype specific and vary between playlists, meaning you can't create your own custom loadout to bring in Matchmaking. You can, however, create custom loadouts for Custom Games. Each loadout has a particular weapon, grenade, and Armor Abilities combination.
