Your responses are predicated on the prior knowledge of where the target is, so that you can light him up at will.
What do you geniuses think is going to happen if you have to light the room up to look for the "bump in the night"?
Unless you're at or near max brightness on your RDS it's going to get washed out from the light. If you think I'm saying stand a muzzles distance from the wall and light it up to see how your RDS does then you were dropped on your head while in diapers.
You went to a class, good for you. I've been to classes, and I've looked for assholes in the dark for real.
I'm not seeking to confirm my suspicions because it's a fact. You go to some class taught by some retired fudd, run around in your living room, and figure that gives you some kind of experience. It doesn't.
I don't give a shit whether you like my answers, hate em, agree or not. I'm done arguing with a keyboard commando.
