One of few alien vehicles reverse engineered by military/civilian engineers working in joint military/militia SR&D facilities. Primary facilities were found outside occupied territory. However, due to dangers of transporting captured equipment, makeshift SR&D facilities were setup throughout the occupied southeastern US. US and other allied forces were hard pressed to duplicate mech and other alien technology.
"Rabid Bear" was part of an enemy scout unit. Militia forces ambushed and destroyed the mech outside Atlanta, GA. Militia took the main chasis (leg components) to mountain base camp. Although non-functional the legs were intact. Engineers integrated the damaged alien hardware with human technology and constructed the first bipedal vehicle. Material was gathered from military posts to construct the vehicle.
The human variant exploited the advantages of execeptional load bearing capababilites of the aliens bipedal design. Nicknamed "Rabid Bear", it was designated in new class of weapon systems: Bipedal Guard - Infantry Support and Assault Mecha (BGISAM).
"Rabid Bear" was heavily armed:
2x side mounted cannons with specially redesigned ammo that could penetrate armor or use fragmentation rounds for infantry support.
2x rear 40 round rocket artililery launchers. Combined, 2 launchers carried total of 80 preloaded rounds and 80 rounds in a cartridge below the launch tubes. The artillery was light but could inflict casualties on light armored/infantry units.
2x side mini-guns for anti-personnel defense
1x lower mounted, twin 30mm chain gun. It could easily take out personnel and light armored vehicles. It had become an effective offensive weapon.
"Rabid Bear" was used in limited offensive engagements. It served more of defensive and recon role for militia and military. Engineers were hard at work trying to mass produce the new bipedal weapon system. Faced major constraints; lack of resources, time, tooling, to mass produce them. Factories were in safe zones distant from the fighting. The logistics of moving the BGISAM's into occupied territory was difficult.
Military and scientists were in rush to better understand the material used in the alien vehicles. Alien technology was taken out of the occupied territories to safe zones in Tennessee, Kentucky, or Virginia.
