The NAM Light Coil Autocannon or LCA is a mass driver based weapon created to take down power armor and light vehicles; primarily in atmosphere when Positron and Plasma weapons are inappropriate. though it is perfectly viable in space where it has an unlimited theoretical range.

The durable and rugged, carbine-styled autocannon is capable of firing 12.7mm rounds making it an excellent weapon for heavy armor users who needed a lighter weapon to supplement their larger ordnance.

It is fielded by the SMDION and IPG. In YE 32, the weapon was withdrawn from field use as it was overshadowed by the extremely popular HPAR. NAM, however, pulled the LCA from combat units following poor performance reviews in comparison to the more powerful HPAR. With large stocks of weapons sitting in their inventory, NAM began playing around with the weapon to make it more functional in the modern military. The issue, he realized, was simply that the LCA could not compete with the HPAR. The LCA's greatest assets were its versatility and much lower recoil. In a NAM Terratech General Combat Armorsuit – “Hostile”, the issue of recoil was compensated for by the platform's mass.

The advent of the Raider made the LCA the first choice of weapon for the smaller, lighter armor. While the LCA would never have the same destructive power of the HPAR, it was clear that the Raider was not a platform designed to be a walking arsenal like the Hostile. This made the LCA the perfect rifle to pair with the Raider.
