True, but if you know you&#x27;re fighting in Florida and they have 3 radars... you probably don&#x27;t need to load the two radars which are known to only exist in Alaska. The world is a big place with many kinds of radars. Or maybe, yesterday, you received new information about the three Florida radars. Wouldn&#x27;t it be good to be able to bring that new information when you head out today?
