This mech paper model is a low poly Partisan, a tank from the real-time tactics video game MechCommander 2 of the BattleTech/MechWarrior franchise, the papercraft is created by Vlmarshall. The size of finished model is about 74 (H) x 193 (W) x 140 (D) mm.
Kallon Industries, famous for designing some of the most popular anti-aircraft 'Mechs in the Inner Sphere, designed the Partisan to bring those same capabilities onto a cheaper, more easily produced vehicle. Dedicated to destroying aircraft, its targeting systems can track up to 200 units at once, compute the optimal target, and link to the targeting systems to other Partisans in the unit. The targeting controls are even removable, allowing its crew to work from a safer distance.
While slow and lightly armored, its role tends to keep it in rearward locations, where this is less of a liability. The Partisan is deployed throughout the Inner Sphere, although most of them are found in the Free Worlds League and Federated Suns. [Source: sarna]
