General Stockwell appeared during the current season. The A-Team were captured by the Imperial Army and faced a court martial followed by death. It was Stockwell who aided their escape from the firing squad, although he may have initiated the capture in the first place. He then made The A-Team work for him in a fixed number of operations before they would receive a full pardon.
Stockwell was a rather shady character to say the least. It was unclear which of Imperial governmental branches he worked for. Now, however, he's a team-member. Again, blame the script-writers.
