When Lt. James is canvasing the area with his troops, the entire scene is a cut-in from The Rescue (1985), most noticeably the lines "Sergeant, that van there, check it out", "I don't want to leave any vehicles in this sector that might be commandeered by the Resistance."
The final scene of "War of Illusions" reuses footage from the end of Breakout (1985) with Lydia saying to Diana, "Better luck next time." The giveaway is Diana's hairstyle which changed considerably in the interim.
