Star Wars The Old Republic: Ultimate War is a mod for Empire at War: Forces of Corruption. It features most of the Old Republic period in a massive compilation of conflicts.

Like its counterpart, the Republic Lance, the Imperial Lance Walker is armed with missile launchers, a heavy blaster cannon, and thick crushing legs. One accessory it has different is the side mounted mortar launcher, excellent at taking out tanks and structures.
Looks good, not too sure about the red markings, though.
@Meyerm just there to provide faction color.
