Tiger Squadron was an elite unit of the New 501st Clone Trooper Legion. They were one of three such units under Shadow's personal command: Tiger Squadron, Blue Squadron, and later Black Squadron. Their ships were characterised by a lifelike image of a roaring tiger painted on the prow.
Like Blue Squadron, they served as an elite attack force waiting in the wings to be called out when extra skill was needed. Tiger Squadron was the more powerful of the two, and its members were renowned as excellent searchers. They vanished for a few years when Shadow sent them on the search for the Legacy, an Old Republic experimental Super Star Destroyer sent beyond the galactic border in pursuit of a CIS mobile weapons laboratory.
