As it's currently implemented, at the end of a key encounter within an Operation, upon looting a high-level opponent, everyone in the Operations group will get an individual container which has a chance to give you a random piece of loot that's specific to your class. It could be part of an armor set, a weapon, and so on. If you don't get loot, you'll get commendations which can be used to purchase gear.
Please note, this feature is currently in Game Testing and may well be modified before launch.
