The M42C Sniper Rifle is a Colonial Marine weapon used for long range combat.
The M42 series of rifles meet the ongoing need for precision kinetic effect in the dismounted combat environment. This capability was understood centuries ago and is clearly described by the International Symposia of Military Operational Research (ISMOR) in the late twentieth century (1994 - Captain I M Mitchell - Sniping and C3I). M42C builds on the success of the M42A incorporating actionable intelligence into the view of the Scout-Sniper on the ground,
The M42C sniper rifle has almost double the range of standard USCM weaponry. It also has the power to penetrate even armored vehicles; it can put a three inch hole in APC armor from several miles away. Unsurprisingly, there are no Predators or Aliens with armor sufficient to stop this weapon’s rounds. With this power comes a price, however – the weapon has a poor rate of fire and is almost useless in close combat situations.
- Despite sharing a similar name, the M42C featured in Aliens vs Predator bears almost no resemblance to the original M42A as laid out in the Aliens: Colonial Marines Technical Manual.
