Pararescue Airmen from the 920th Rescue Wing conducted a pre-deployment mass casualty exercise Sunday, officials said.
Officials said they performed the exercises at the south end of Rescue Road on Patrick Air Force Base.
Officials said the training included live weapons firing with blanks.
Residents potentially heard loud weapon noises within the Rescue Road area, and off the Banana River shore area, south of Patrick's Outdoor Recreation Marina, officials said.
During the exercise, the trail along the Banana River, south of Building 698 (the 308th Rescue Squadron), was closed north to the catch basin, before the entrance to the Family Camping Ground. The exercise prepared the Pararescue Airmen for potential scenarios they could face during their upcoming overseas deployment, officials said.
The 920th Rescue Wing is an Air Force Reserve combat-search-and-rescue unit
which trains and equips its Airmen to save lives.
