Nod Vertigo Bombers taking a juicy bite of hostile base's power grid.
All in all Vertigo Bomber's stealth makes it quite useful even against AA (detection range is rather small, small enough for Vertigo to drop its payload the same moment it gets detected). Faster targets can evade its bombs though. Usually ignored note is that they can attack air targets with their rear guns (No match for real fighters but can be used against other ground-attack in a pinch).
And after an upgrade they can even make ground units invisible with Disruption Pods (Exploitable with Reckoner APC and Saboteur for building stealing), but for a limited time duration.
