Established in 2881 in Lovell City, Luna, Armstrong Arms was a staple in Lunite weaponry from the 2940's until 3003, branching off to Lunar City, Tycho Base, and Greenville, New Luna. When the Moebius Effect took place, they temporarily transferred their headquarters to Greenville. When the original Luna returned, it was discovered that the headquarters in Lovell City was destroyed beyond repair. Armstrong is now struggling to consolidate their assets and rebuild.
