A third-generation Armored Patrol Unit (APU, not from the "Matrix" movie) the Lynx is a huge step up from its predecessors, but still failed to live up to fleet standards. It was replaced quickly by a better and larger mech, and all the -22s were relegated to secondary roles. However, the Death Guard saw the -22 as the apex of their "Strike-hard-and-run" philosophy and requested as many as possible for their armored core. Happy to oblige, the High Command issued over 3,000 to the DG which were immediately repainted and specialized to scores of roles from "Mech snipers" to flamethrowers. They were perfect, hard to hit by tanks because they are too fast, and tough enough to stand up against heavy small arms fire.
