You said that the ARENA system as a covering arc of 300 degrees, which area of the tank is located in the 60 degrees that aren't covered or does the AREA array rotate so that no one part of the tank is constantly without coverage? Also, since urban areas seem to be an increasingly common place for tanks to go and the opponents that they are fighting are usually militia with only basic AT weapons, will this system be able to counter dumb fire AT weapons like RPG's, SMAW's or LAAW's, or even wire guided missiles that don't use laser targetting?
