Lieutenant Kilfeather interrupted her. "Mirage knows the regs, Specialist. And she may be from intel, but she's still Air Service, and when you're up there, as part of a flight, it's just call signs, covering your wingmate, and following the leader. You don't have time to salute the rank. If you do that, you're dead." He nodded at the sergeant in acknowledgement. "While we're working together as a flight, without anypony else around, then I'm just Icepone, or Ice, and I won't expect salutes, and Mirage won’t expect you at ease."
