Maybe I'm missing something but very seldom I hear those guys having a conversation with someone. They go on and on and no one can get a break.
You are exactly correct. The whole theme isn’t really to “communicate” so much as it is to be heard over everyone else. Ideally, there would be at least one, or several other people trying to talk, so that there is someone to key on. The only real communication is sent back to the person that was being talked over, indirectly...“You said tell him you was on a driver, and when you got up I got down, cause I heard it all”...and that type stuff.
It’s basically an unending pee contest over the airwaves.
