TANGO DOWN — what does it mean? It is a slang phrase used by the Special Forces when a terrorist has been eliminated in combat. But what is that TANGO anyway?

Even with modern straight and clear electronic communication via Skype or email, phonetic alphabet is often helpful. Besides, sometimes it is cool to use it, as for the Jester Joker.
