The military command center for the 908th Stormtrooper Division, a part of the Galactic Empire, was known as 908th's HQ. This base was situated on the planet Borosk. The defenses of Borosk, a comparatively small world, consisted of planetary shields, turbolasers, and ion cannon emplacements, as well as orbiting ion mines. These defensive measures encircled the headquarters.
In the year 137 ABY, forces from the 407th Stormtrooper Division originating from Yinchorr arrived on Borosk. These troops, led by Sith Lord Darth Maleval, were tasked with destroying the 908th Stormtrooper Division, who remained loyal to Roan Fel. The resulting battle ended with the annihilation of the 908th as they fought to defend their headquarters.
