Alien military employed vast array of military hardware. The Medium Anti-Grav Assault Tank (MAGAT) was most widely deployed medium tank on Earth and formed the spearhead of the invasion; a role traditionally reserved for the heavy siege tanks and MBT's in prior conflicts.
The MAGAT was armored, fast (speeds up to 150 mph), highly maneuverable, armed with high powered plasma cannon, and a rapid fire anti-personnel gun. Its counter measure system employed sensors -tied to the nav computer- which detects incoming projectiles and forces extreme, evasive maneuvers aided with side boosters.
The armor was able to withstand direct fire from human tanks including the US M1 Abrams MBT (to some extent).
USMI classified vehicle: anti-grav propelled tank. Anti-grav tanks more agile and not limited to "hovering" a few feet off the ground. Unique to the MAGAT, the anti-grav and smaller size gave ability to execute high/low altitude air drops from transports.
Air Drops drew a lot of power maintaining stability and increased stress on propulsion system during descent (dependent on altitude and planet gravity) In the end, its daily operations, no different then its hover tank counterparts.
Alien leadership did not regard the MAGAT's as anything special. Simply an assault and security enforcement vehicle (riot/crowd control ops). But, against "primitive" human weaponery, they considered MAGAT's effective to lead attacks on global targets.
As war dragged on for several years weak points were identified on the MAGAT. Plasma cannon had slow rate of fire; not beneficial alone against group of human tanks. Cannon disables if overheats. The driver compartment highly exposed with little secondary armor protection. Targeted, repetitive fire on the hull, US M1 Abrams and German Leopard A-6 succeed at neuatralizing the MAGAT's.
MAGAT is smallest of alien armor. It still is a powerful tank to be reckoned with in combat.
