Capt. Sylvester D'Agrella briefs the Joint Base Charleston Honorary Commanders after demonstrating the Percussion Actuated Neutralizer outside the 628th Civil Engineer Squadron explosive ordnance disposal building July 14, 2010 on Joint Base Charleston, S.C. The PAN is a high-velocity, precision tool used to disrupt IEDs with water, air, or steel shots. This is the tool of choice as it allows flexible, surgical shots to be taken to prevent a detonation and preserve evidence for law enforcement officers. The honorary commanders toured EOD as part of a base orientation tour to learn more about the missions performed by different units on Joint Base Charleston. Captain D'Agrella is the commander of the 628 CES explosive ordnance disposal team. (U.S. Air Force photo/Senior Airman Timothy Taylor)
