M12 Warthog APC
From Halopedia, the Halo wiki
The Warthog Armored Personnel Carrier is a United Rebel Front ground vehicle.
It is an uncommon variant of the standard M12 Warthog LRV, and is essentially a standard M12 Warthog, but with a passenger section capable of holding ten passengers bolted between the driver section and the chaingun section.
One was seen in use by the United Rebel Front on the planet Victoria in the 111 Tauri System by the SPARTAN-IIs of Blue Team in a field mission.
