Task Force 99, also known as SCAR Squadron, was an elite Imperial stormtrooper squad in the 501st Legion led by Sergeant Kreel. One of their missions was to investigate Sunspot Prison, an installation that was recently abandoned by the Alliance to Restore the Republic.
Task Force 99 was named after Clone Force 99, also known as the Bad Batch. Both squads were comprised of members, of which each had a specialization, making them distinct to others in their particular corps.
