“Reaver Captain” is a rank of the Fallen.
They are the field leaders of the Fallen. They use the heaviest armor of all field Fallen and will almost always lead the charge in terms of the battle. Whether this stems from a lack of fear or just an exemplary level of pride among the Fallen and their battlefield conduct.
Incendiary projectile weapons
Captains will command the tactics of the numerous Fallen around them. They favor melee oriented combat. They are protected by Arc Shields. This shield will regenerate given long enough.
High level Captains can warp across the battlefield in a manner similar to Hunters.
