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. Each loadout has a particular weapon, grenade, and Armor Abilities combination.
