T4-B Heavy Tank

The T4-B Heavy Attack Tank was used by the Rebel Alliance during the early stages of the Galactic Civil War and continues to see use after its reorganization into the New Republic. The vehicle is one of several designs that was acquired by the Alliance from a splinter group within Yutrane-Trackata. It is now being manufactured under the banner of the Republic Engineering Corporation.

The T4-B is one of the most heavily armed vehicles fielded by the New Republic. It mounts starfighter-class weaponry and is meant to take out the largest threats on the battlefield. The T4-B provides enough of a punch in conflicts to withstand significant ground forces and is capable of defeating most ground vehicles arrayed against it, although it has difficulties surviving direct assaults on vehicles like the AT-AT.

As powerful as it is, the unit does have significant drawbacks. Its tracked design limits its mobility (though its mass and power more than offset this flaw) and is expensive to produce, meaning that it is rare to see more than a handful on the battlefield at any one time.
