M808G5 Scorpion Main Battle Tank

The is a UNSC tank in use with the UNSC Marine Corps. An offshoot of the Scorpion design, it was used as an expeditionary tank, where the lighter armour, and armament allowed it to be quickly, and more easily deployed on an expeditionary role. More than a match for both Covenant and Insurrectionist alternatives, the M808G5 is a reliable and rugged expeditionary tank. The G5 modifications have closed the gap in terms of protection, armament, and technology with the generally superior M820 Scorpion, extending its service life until the M820 replacement program can be completed. 
The M808G4 can be armed with sponson mounted weaponry to improve its performance for special purpose missions, and, like all Scorpion platforms, can utilise the Unified Command Mountings to swap the turret and internals to change platform, such as converting to the Wolf Spider Air Defence System, or the Panther Close Assault Vehicle.
