MX4 Light Support Weapon

"Nothing beats streams of plasma."

- Major Hartigan

The MX4 LSW is the second UNSC directed energy weapon issued to their personnel. The Weapon is made from a lightweight polymer with a firing assembly made from frictionless materials and four heavy cooling fins made from a extremely heat resistant ceramic polymer lattice with rubberized. In its standard equipment it comes with a SUCOG Site as standard

Uses
The Weapon was first issued to frontline troops fighting Brutes in the Remnant forces. The weapon was well liked because of the punishment it could bring down on their shielding. It was increasingly issued in a position similar to the M122 LMG. Since it was accurate and had a hefty rate of fire it was used primarily in supporting roles.

Operation
The MX4 uses Camium Telluride pellets in a 120 round magazine, which is fed into a ionization chamber where a impulse laser ignites the pellets and vapourizes them into super heated gas. The weapon's barrel is laced with magnetic coils which creates a magnetic 'tunnel'. The plasma is volleyed down the tunnel and spat out a 5000 m/s. The weapon can fire continuously for between fifty-sixty shots before it overheats. The laser cuts off, the magazine is sealed off and the cooling fins fan out, venting the heat into the air. In some cases, it is said to feel like warm air and in more extreme cases it produces a gout of flame. The Ceramic plates can, at best, become lukewarm, though continually dump the heat energy into the air, venting it away from the rifle. The magazine is sealed off to prevent it potentially catching fire and exploding, as is the power core.

UNSC Comments
"Scary gun, SCARY gun! I overheated it during OPERATION: GROUNDHOG and it spat out a torrent of flame! Flame dammit! Apparently thats it igniting the gases in the air its that hot."

"Thank god those Covies hardly use thermals. Under continual fire, the weapon shows up as a massive red spot, the very air heating up."

"All the heat is vented forward, in the idea that the enemy is ahead. A few guys have been scolded by it, worst case set fire, though nobody is stupid enough to do it these days. I still like having a heat regulating body suit with me, keeps me cool while everything heats up."
