The content includes six new battles briefed and debriefed by the members of the Edy Detachment, one for each infantry class and a finale combining aspects of the previous trials.
The battles themselves will often have you facing off against a numerically superior Imperial force, usually without tank support and always without command orders. They take place on one of the maps previously in the main campaign, with brand new enemy aces and capturable imperial weapons.
Each trial is a challenge from a member of Edy's Detachment, however the player is free to choose who is actually deployed onto the battlefield.
