M12A1 LAAV Rocket Launcher
From Halopedia, the Halo wiki
The M12A1 Warthog LAAV (Light Anti Armor Vehicle) is only seen on Halo PC, and mounts a 102mm SC-HE Rocket Turret.
Introduction
Warthog is a generic term for a lineage of United Nations Space Command ground vehicles. It is affectionately known as the 'Hog by UNSC soldiers. The Warthog is the modern-day "Jeep": all of its variants are equipped with a seemingly full-time 4x4 transmission, the ability to turn its front and rear wheels to allow for tighter turning, and can carry 3 people; 1 driver, 1 gunner, and 1 passenger.
The M12A1 Warthog LAAV is basically a M12 Warthog, but the M41 LAAG is replaced with the 102mm SC-HE Rocket Turret. This gives UNSC personnel a higher degree of anti-armor capacity.
The driver has no forms of attack except ramming enemies with the Warthog itself, which instantly kills an enemy on foot in Halo: Combat Evolved. The gunner stands on the back of the Warthog and mans the SC-HE Rocket Turret.
Its role as the primary UNSC LAAV is usurped by the M12G1 Warthog LAAV in Halo 2.
Description
The M12A1 Warthog LAAV handles exactly like the M12, but it is painted black with a yellow stripe to distinguish it from the M12. The 102mm SC-HE Rocket Turret also resembles the M41 LAAG to some extent, but it is a triple-barreled rocket launcher.
