They knew they were gonna be attacked by drones on home soil, right? Or is it standard procedure for militaries to “camouflage” their stuff deep inside their own territory? It’s probably not very easy to cover all of these planes with tires and even some metal grids (looked very ghetto, by the way).
If Intelligence knew and couldn’t do shit there will be some heads rolling as is us usual procedure in Führers Reich.
That I don’t have an answer to.
