Terminator 3: Hunt

Miles ahead, John Connor, in the driver’s-side backseat of his Humvee, saw the T-850, Glitch, tilt his head. The movement was uncannily like that of a human trying to hear something better, and it was for very similar purposes. The Terminator would be trying to get an optimal orientation to improve his reception of distant audio stimuli.
	“What is it?” John asked.
	“Gunfire,” Glitch said. “Multiple shots. Small arms. Miles away.”
