Minus Ten and Counting!

Well, how useful that would be depends on the radius of Doug's AoE, since either the radar stations to be spoofed or the beneficiary of the effect would have to be within that area. If Doug were at a radar station, there would be simpler and possibly subtler methods of disabling it (whatever "Surprise!" winds up doing, it should be double-plus unsubtle). If he were covering his allies directly, he'd probably have to be flying with them.
