Even if the spotters can't get quite this small, its over, isn't it? Being infantry is going to be absolutely terrible in 20 years.
Even if you have lasers and interceptors and even a screen of drones to protect your airspace, war is just going to be about whose interception capabilities run out first, and then robots with full EM spectrum sensors at every angle are going to rape you with self guided munitions.
