There is the unspoken assumption here that several methods are used to guide airdrops to the proper location. All of them coupled together are strong against any attack which targets one. Something else is that specifically there would most likely be markers (infrared fireflies, colored flares, smoke, etc) that would be used to signal the drone in the first place. The infrared spectrum is still phenomenally useful because of the barrier to entry the technology has for utilizing it. If you see a flashing infrared signal, it is almost a certainty it's US or "allied" forces. Kinda tangential but interesting.
