What base has the hardest boot camp?

THE MARINE CORPS IS THE TOUGHEST BOOT CAMP OUT THERE AND ONLY THE TOUGHEST SURVIVE. THERE IS NO IF ANDS OR BUTS.

Responses to this will vary depending on the service. Typically and traditionally, Paris Island, South Carolina for the USMC is considered one of the toughest.

I will say, the Marines are very tough, but the Army is right up there with it, and the Air Force, is becoming way more like the Army and the Marines in that their PT is just as challenging, they learn the EXACT same stuff the others do, tactics, rifle usage, etc. The same amount of stress is put on them, and they carry the same attitudes that you Mighty Marines do. Marines probably have the toughest boot camp with the Army right there with it, followed by the Air Force.
