Given the scope of damage done to the Tempesion galaxy during the Afterwar, one can only assume that ARC and GEMeni could not be the only organizations performing reconstruction.
Granted, they are the largest, but there are several powers which refuse to be overlooked.
The Apex Corporation is one such company, which excels in not only terraforming technology but also MAV production. Apex colonizes the worlds that ARC is too busy for and GEMeni views as just plain "unimportant."
Their sizable private army is mostly comprised of mechanized infantry, much impart due to the necessity of MAV technology needed for advanced and quick terraforming.
The J20a Falchion is Apex's top of the line MAV, which blurs the line between the more formidable (advanced modular anatomy vehicle) AMAVs and traditional MAVs. Affordable pricing and reliability / versatility make the machine an "AK-47 of MAVs."
The Falchion stands about 13 feet tall on average, though different configurations and generator backpacks may vary the dimensions of the otherwise compact machine.
While it lacks the incredible maneuverability and boost-power of AMAVs, it does have a finely-honed control system, utilizing the advanced controls of AMAVs for limb movement. However, unlike AMAVs, the Falchion has no kinetic shielding or boosters for quick movement.
Modular weaponry includes an assortment of combat rifles, CQB machine pistols and melee weapons, anti-MAV rifles and even shoulder-mounted railguns.
For defense, the MAV has a composite armor plating and reinforced metal plates on the shoulders good for deflecting small arms, but the real defense lies in the machine's ADS (active defense system). The ADS is capable of scrambling the lock of almost every tracking munition, "killing" the projectile and rendering it a "dud."
