Look up MANPADS[1] and find out what that is, it appears to pretty clearly satisfies (A).

Then look at (B) and note a launcher that merely intends to launch something that satisfies (A) counts, and then note he straight up calls it a MANPADS launcher prototype. There is no requirement that it actually be capable of doing so.

Also note in his other short, the guy shows a network of cameras doing tracking of a drone[2] and claims that is an intended guidance system. He claims the guidance is updated to the rocket while in flight, with his diagram clearly showing the target as the emblem of an aircraft.
