A powerful siege tank.
The armor is made of mix of Stygium, ceramics and other materials to create a light but strong composite armor. It has one main cannon on top that fires NS-Siege Shells. Its powered with an rechargeable but powerful electric engin and runs on two tred belts.
The Hydra tank is ment to take out fixed defences, not moblie enemies. Its treds are positioned so it can easily traverse over ditches and fortifications. Its Cannon takes out the forifications . It only needs about half a squad to crew it.
The original idea was from the star wars AT-TE but evolved to be more like the M1 Abrams tank. While the Chimera Tank is ment to take out enemy personel they Hydra is ment to take out buildings fortifications etc..
