Jillian was holed up in a defensive position in the desert, having high ground over the Zeon forces that would be coming in pursuit of her, rather to capture her or kill her she didn't know. "here they come..." From her superior position, Jillian had almost no trouble at all with unleashing a few tactically and masterfully aimed bazooka rounds that would put out the leg joints of the zakus that were closing in on her position. No matter what happened, Jillian would ensure that none of her shots were fatal. Defector and traitor as she might be, she still didn't have the stomach to kill her own former comrades and friends.
