I see this often in language now. Someone on another thread used the phrase 'absolutely zero environmental control' where I would have said 'no aircon', people say 'improvised explosive device' instead of 'bomb'. Why is there a need to be this explicit in everyday usage? For the military, maybe, I don't know anything about that, but why not keep the communication short and sweet? Words can mean different things but you can tell what the speaker/writer intends from the context, so why tediously spell it out everytime?
