The M12 Warthog has, for the most part, resisted all attempts at being replaced, its flexibile and robust nature consistently outperforming all of its closest competitors. Nevertheless, in 2549 the UNSC Army asked Project EXCALIBUR to include a supplement to their own light reconnaissance vehicle fleet - the Warthog was still popular among the Marine Corps, but the Army felt it was time to upgrade to an improvement. The result was the M14-X Caracal, a light truck with troop capacity and a rear-mounted M247 GPMG, designed for light reconnaissance and patrol, as well as urban combat and fire support. Though a successful design, the destruction of Reach put an end to its adoption.
