FOB DELARAM, AFGHANISTAN – In the middle of southern Afghanistan, a group of Marine officers have just completed an arduous six-hour meeting.

When battalion commander Lt. Col. Maxwell "Zip" Zapolski asks if anyone's got any saved rounds, S-6 communications officer 2nd Lt. William Ross stands up.

"Sir," he begins nervously, "I've completely messed up the communications gear EDL, and we're going to have to do a battalion-wide inventory."

Lt. Col. Zapolski knowingly smiles and calmly pushes a button, opening up a trap door beneath 2nd Lt. Ross and sending him plunging into a tank of water, filled with 300-pound, man-eating sharks.
