Thrawn's Revenge is a large-scale mod for Empire at War: Forces of Corruption. It includes the events of the Galactic Civil War after Palpatine's death at Endor, up until the signing of the Pellaeon-Gavrisom treaty. If you own the Steam version of EaW, you will have to complete extra steps to run the mod after installation. Please see the manual for these steps.
An Imperial task force deals with some Corporate Sector uprisings.
Now that's a pretty varied Imperial Task Force. If I spot it correctly from left to right there is first a Tector, then (obviously) a Venator, an ISD-I, an ISD-II and another Venator.
The Dreadnaughts seem to be CSA ones.
