Assault transport.
The Wraith Invader is an infantry fighting vehicle available to Warlord Pavium. It is armed with a siphoning beam, which repairs the transport, and can carry two units of infantry. Each of the infantry units can fire out of the Wraith Invader. In addition to standard vehicle upgrades the gravity propulsion system of the Wraith Invader can be boosted with Carrier Overdrive, significantly increasing its shield strength and damage.
In the Covenant, ecclesiastical authorities ultimately oversaw even the most trivial modifications to existing designs. Improvements or alterations required layers of bureaucracy to navigate, and often took decades to gain approval from the Prophets. The Banished approval process is much simpler: if there is a demonstrated need and materials available a pack leader can make any changes that he or she wishes. The Wraith Invader is an example of this freedom, with Pavium taking damaged mortar tank hulls and repurposing them into heavy troop carriers.
