Machine Gun (Portable)(Support Weapon)/RPG3e
Essentially a generational improvement over the Man-Portable Medium Machine Guns or General Purpose Machine Guns of the 20th Century. This weapon fires rifle rounds in the vicinity of 7.62 mm or 0.30 calibre. This calibre of round is better able to damage BattleMechs, BattleArmor and Combat Vehicles. Portable Machine Guns are light enough to be carried and fired by a single trooper and are often deployed alongside grenade launchers. Consuming more ammo than Long Arms that use the same calibre, units that use the Portable Machine Gun as its support weapon are more firmly tied by their supply chain.
