Federation's on-ground weapon.
Federation's fleet from north hemispheresouth and Imperial fleet from hemisphere cruise thousands of kilometers and fight on the equator, thus there is no demand of "Tanks".
However, in the last 10 years, both forces became more aggressive for occupy cities and fortress. This situation made them develop new weapon, tanks.
The engine is pure Arkilian (made in Federation). They used some parts from ancient engine thus it generates really small amount of buoyancy, this let their weak engine move this "iron box".
My first attempt of drawing tank on dA.
I got many inspiration from my favorite Hungarian tank, "43M Zrínyi". Don't say it is almost same!! I do love the tank shut up!! XD lol
