The M4A3 Vánagandr (ヴァナルガンド, Vanarugando?) is the staple Feldreß of the Federacy. The third-generation Vánagandr is said to be superior to the Ameise and Grauwolf of the Legion, though slightly inferior to the Löwe. Its design features a tandem cockpit, manned with a driver and a gunner/unit-commander. All crew members must wear an armored exoskeleton when operating the M4A3.
Vánagandr is an alternate name of the legendary wolf Fenrir from Norse mythology, meaning "Monster of the river Ván". Its designation of M4A3 stands for Model 4 Alteration 3.
The Vánagandr is outfitted with a 120 mm smoothbore gun as it's main armament, with double 12.7 mm heavy machine guns to each of its sides. The tandem cockpit is comprised of two seats adjacent to each other, the right for the driver and the left for the gunner. The total weight of the unit is 50 tons, mostly attributed to its heavy composite armor.
Although it is described as sluggish, the Vánagandr possesses a cruising speed of nearly 100km/h, comparable to that of the Löwe or Reginleif. The reason it is described as slower than its contemporaries is its slow acceleration and limited agility.
- The sluggishness of the Vánagandr makes it utterly incompatible with the fighting style of the Eighty-Sixth Strike Package, its Processors do not hide their dislike for the machine.
