They already came up with something similar to protect their bases in the Green zone against mortar attack. These radar guided mini phalanx guns don’t shoot birds either because they’re programmed to only look for shells coming in a certain trajectory.
I read a little about that system. They are not talking much about how well it is working. I think it was a full sized Phalanx system which for a base might be what they need.
Just send it to Japan and have it come back 1/10 the size.
Really.
