During the Great Galactic War after the Sacking of Coruscant, 2 Imperial commandos ambushed Jedi Satele Shan on a transport ship but were slain in the process.

Imperial Commandos on Makeb
Imperial commandos were trained and used by Imperial Intelligence in many operations to undermine Republic Strategic Information Service and assassinate high priority targets. Notable Imperial Commandos include Cormun, Kalmic and the Shadow Captain. Imperial commandos wore a heavily armored uniform with a helmet very different to that of a standard Imperial soldier. Most Imperial Commandos wore light grey and white armor. However, Korriban regiment members wore red armor.
