Transform into a stationary turret when destroyed with 200 hp
An interesting contraption, the Spartan is a self-propelled automated turret. It can traverse the battlefield easily and once its severely damaged, it burrows itself in the ground as a stationary turret and then bares a striking resemblance to the Guardian Cannon in the previous war.
Essentially a turret on tracks, the Spartan Tank is armed with a cannon and is rather slow moving. It has also less health than most other battle tanks like the Hunter, Sheppard or Avenger. However, once it reaches 0 health, it turns into a stationary turret with 200hp, trading its mobility for vastly increased armour. Its cannon is good at piercing Medium-type armour but is less effective against heavy armour and light units/infantry.
In its mobile form, the Spartan Tank has Medium-type armour that is, itself, weak against cannons. However, in turret form, it switched to Heavy-type armour, which is weak only against lasers.
The Spartan Tank's Nod counterpart is the Centurion. Incidentally, there is an achievement ("Classical Warfare") for destroying a Centurion using a Spartan Tank.
The cannon seems to be based on the Guardian Cannon in CNC3.
