Marines 'ran back into the fight' during shooting, official says

FBI investigators work the scene of the July, 16 shooting at the Naval Operational Support Center on Amnicola Highway on Saturday, July 18, 2015, in Chattanooga, Tenn. U.S. Navy Petty Officer Randall Smith died Saturday from wounds sustained when gunman Mohammad Youssef Abdulazeez shot and killed four U.S. Marines and wounded two others and a Chattanooga police officer at the Naval Operational Support Center shortly after firing into the Armed Forces Career Center on Lee Highway.

Twenty-two servicemen were working at the U.S. Naval and Marine Reserve Center on Amnicola Highway last Thursday morning, making sure their gear was clean and in working shape.

It was an unusually high number of Marines for a normal weekday at the reserve center.

The station is primarily occupied by Navy staff, but is also home to 10 active duty Marine staff members with the Battery M, 3rd Battalion, 14th Regiment - better known as the Mike Battery.

The number of military members at the Amnicola center may swell, depending on what training takes place any given week. And on July 16, it had.
