M6/E Spartan Laser
From Halopedia, the Halo wiki
The Weapon/Anti-Vehicle Model 6/E Grindell/Galilean Nonlinear Rifle (W/AV M6/E G/GNR), colloquially known as the M6/E Spartan Laser or the E ("Enhanced") model M6, is a variant of the M6 Spartan Laser directed-energy weapon manufactured by Misriah Armory and used by the United Nations Space Command.
The M6/E Spartan Laser is one of a myriad of variants of the M6 Grindell/Galilean Nonlinear Rifle, an initially exorbitantly expensive weapon which underwent several refinements and iterations to reduce its cost. As with all variants of the Spartan Laser, the M6/E has an integrated and smart-linked Wyrd III optics suite, capable of 3x magnification. Manufactured after the Human-Covenant War, the M6/E is installed with miniaturized components derived from the M6 variant originally mounted on the chin of the AV-22 Sparrowhawk. Despite functionally just as capable as other variants, the M6/E is an order of magnitude cheaper to manufacture.
The M6/E was upgraded to combat heavy armor, and functions primarily as an anti-tank ordnance. In the wake of the Created conflict, the M6/E became the variant preferred by UNSC Infinity's Spartan-IVs to combat the emergent Forerunner threats.
The M6/E Spartan Laser is featured in Halo 5: Guardians as a usable weapon known as the Spartan Laser. It is a power weapon, which fires a powerful laser that deals an incredible amount of damage, destroying all vehicles with a single well-placed shot. The Spartan Laser is one of the most powerful weapons in the game, and to compensate, it has a limited use of four shots, a short cooldown after a discharge, and inability to pick up ammo.
The Selene's Lance variant of the M6/E Spartan Laser is likely named after the Greek Goddess of the same name.
