Plant a loud, incoherent, emotionally charged agent posing as a supporter for something you don't like in order to discredit their unwitting supporters.
Not asserting Alex Jones is doing this, rather that this type of tactic is not uncommonly used.
Even if his personal claim about military and intelligence connections are true, it isn't evidence of anything, as you alluded. For example, most of the people he has connections with could also think he is a crazy wingnut.
Also, his clips about the frogs being turned gay makes me laugh every time I see it. That and when he tears his shirt off in rage at the globalists and runs off into the night.
