If I was an in intruder, the sound alone would tell me as someone said before, your location, how many rounds you have more or less, your lack of armor penetration, ect.
The only sound I should be hearing is silence.
Bah! The question posted as the OP questioned..it's not outdated and the sound will definitely send shivers. By the time you're generating that sound you and them intruder most likely know what's happening. Yea silence is key, to a point..
