The Civil Model-393 Heavy Precision Carbine, shortened to CM393 Marksman Carbine and simply dubbed the "Sniper-Carbine", is a distant variant of the M392 DMR for use in Police Departments on human colony worlds. Though it's basic workings are the same as the DMR, it has a number of "additions" to better suit the needs of its owners, where the ability to quickly change and adapt to changing circumstances are better appreciated. They are given out as standard-issue to police snipers and even found regular use in SWAT teams. Ironically, as the war progressed, many CM393s have found their way into the criminal black-market, stockpiling them for the inevitable uprising that occurred after the Human-Covenant War.
