FORT A.P. HILL, Va., - More than 35 first  responders tested their ability to react under pressure to a simulated armed gunman  during an active shooter exercise during preparations for the Boy Scouts of  America's 2010 National Scout Jamboree July 23.
The exercise simulated a disgruntled father in search of  his children, forcing his way onto the post past Army military police members,  guarding a mock-up of the Rappahannock gate, said Stephen Fogler, senior  defense analyst at Standing Joint Force Headquarters, U.S. Northern Command. 
After fleeing his vehicle, the shooter opened fire on  Soldiers and took a hostage in a small container, designed to mimic a visitor's  control center.
"Between the extreme heat, the large number of  Scouts and guests and the high operations tempo required to make the event a  success, Jamboree combines a variety of stressors for personnel," Fogler said.  "It's critical for our police to be able to respond quickly and make  rational decisions to protect our guests." 
During the scenario, the perpetrator, portrayed by Army  Staff Sgt. Greg Small, simulated wounding three Soldiers with an AR-15 assault  rifle before taking a hostage inside the container. A team of Army military  police surrounded the small box, using negotiation and de-escalation tactics in  an effort to mitigate further injuries or loss of life.
"It is critical to introduce stress into the  situation to make it as realistic as possible," said Sergeant Small, a New  Jersey National Guardsman from Company C, 114th Infantry. "In this  situation, the conditions will make a shooter less rational as time passes. A  cornered gunman in a sweltering room will get desperate and more  dangerous."
Equally as important to resolving the conflict is the  rapid and successful migration of wounded personnel to the nearest urgent care  center, nearly seven miles across post at Wilcox Camp.
"The size of the installation creates more time for  the situation to deteriorate," said Fogler. "Personnel must respond  quickly to ensure any wounded personnel receive treatment as soon as possible.
While effectiveness, efficiency and rapid-response are  key, Fogler said the exercise was more for training, not evaluation.
"The Jamboree brings together Title 10 and Title 32  service members from all branches who need to work together in a hectic environment,"  he said. "The BSA has been astonished with our abilities over the years,  and we will continue our dedication to their safety."
