M312 Elephant

The M312 Heavy Recovery Vehicle, commonly referred to as the Elephant, is a UNSC Mobile Assault, Support, and Recovery Platform. The vehicle is used primarily as an armored mobile recovery vehicle and has seen action most notably in the Human-Covenant War.

Background
Designed and manufactured by JOTUN Heavy Industries, the Elephants were initially used in the utility and farming industries during the early colonial expansion periods. After several decades serving in the civilian market, JOTUN was contracted by the UNSC to develop the Elephants and build them as armored repair and recovery vehicles. In the years since, the Elephant has been modified into several variants and upgrades, though the Elephant's basic design philosophy and versatility remain unchanged.

Design details
The M312 Elephant is designed to safely transport troops, equipment and light vehicles to and from the battlefield. On one occasion, a single unit was able to pull an entire Shaw-Fujikawa Translight Engine by itself. The M312 also features a protected rear bay, providing more protection to its onboard personnel and equipment than the M313. The vehicle is fitted with three M41 Light Anti-Aircraft Guns as its primary defense/offense weapons system and can be equipped with an overhead M247 light autocannon.

Operational history
When the arrived at the Etran Harborage in pursuit of the Covenant Arbiter Ripa 'Moramee, who had captured Ellen Anders, the UNSC forces onboard utilized three of the M312 HRVs to perform reconnaissance on the shield world's surface. Two of these were captured by the Flood, but were rescued under the leadership of Sergeant John Forge and Spartan-II Red Team. These three M312s provided support in the battles on Shield 0459's surface. When the UNSC forces were recalled to the Spirit, Bravo Platoon was accompanied by an M312 HRV. After Pelican Victor 397 was shot down by Covenant forces while pulling the Spirit of Fire's Shaw-Fujikawa Translight Engine reactor to the Apex Site, Captain James Gregory Cutter decided it was too dangerous to use an airlift to transport the reactor anymore. Instead, Forge decided to use an Elephant, the only ground vehicle with the mass to pull the reactor. The Elephant pulled the reactor up a series of ramps guarded by Covenant citadels before backing the reactor onto a slipspace translocation pad. The pad teleported the reactor to the Apex, leaving behind the Elephant which was outside of the pad's range.

M312 Elephants were used during the Battle of Earth. In 2554 several Elephants were used to help evacuate wounded servicemen during the Battle of Draetheus V.
