Staff Sgt. Joseph Stoltz, 11th Security Forces Squadron military working dog handle, prepares his k-9 Lana, an 11th Security Forces Squadron military working dog, to demonstrate a controlled aggression scenario on volunteer Chuck “the ice man” Lidell, mixed martial arts legend, during the 2011 Joint Service Open House here. JSOH affords the public an opportunity to meet the men and women of the Armed Forces and to see military equipment from the Navy, Marines, Army, Air Force, and Coast Guard. JSOH is planned and conducted through the efforts of active duty, guard and reserve service members, as well as civilian employees, retirees and family members.
