NightStalker Helo

She's designed to approach the target quietly at extremely low altitudes.   Typical tactics involve landing the craft within 3 kilometers of the target, then crawling the remainder.   Final stage of the attack involves strike-and-fade doctrine with a lightning fast egress.  She can also deploy a four-man strike team, then loiter or hide in a quickly made "beetle den" that the legs are programmed to dig out of the ground.
