The 317th Tactical Unit was a combat force from the Imperial Security Bureau, colloquially known as The Wolfpack. The unit was attached to the Nebulon-B Frigate
Swiftsure, under the command of Colonel Verus Theus and charged with operations against increased attacks by Rebel insurgents on Brentaal
This unit consisted of ten squads of ISB agents, accompanied by two squads of
ISB Stormtroopers. In total it contained the equivalent of two or three platoons of troops, less than one full company, though it was an autonomous command with full intelligence support.
The tactical unit was equipped with a cadre of small spacecraft for use on covert missions. They appeared unremarkable in nature but were extensively upgraded with advanced equipment, arsenals of military hardware and infiltration devices. Several outdated shuttle transports and a handful of light freighters were all contained within the
Swiftsure's hangar, and the frigate itself featured a comprehensive intelligence and control center.
Dedicated to the ideals of the New Order, ISB tactical units operated outside the typical chain of command and considered their own objectives as paramount those of the Imperial Navy and Imperial Army. Such units were generally comprised of personnel from various ISB divisions, such as Enforcement and Surveillance. The members assigned to these commands were highly-trained elite troops, in contrast to the expendable soldiers of CompForce.
