Question for our DU Marines:

I served in the Army, where our drill sergeants spoke with a 'normal' voice; loud, abrasive, and authoritarian, but 'normal'.

In the past, I've seen bits from those military reality shows, including the ones featuring Marine boot camp. The drill instructors all talk in fake, cartoonishly gravelly, snarling voices that made me want to laugh my ass off.

Now, in the movie Full Metal Jacket, R. Lee Ermey (a real Marine) spoke in a voluable, highly-profane manner, but it was still more or less a 'normal' voice.

So, do Marine D.I.'s really speak in that idiotic, raspy, tough-guy voice from the TV shows? Or was that more un-reality from a 'reality' program?
