The biggest fall since World War II occurred in Germany. Operation Titan Rhino, which lasted seven weeks, involved more than 2,500 British and French troops. At the Sanlager center, they practiced operations against a simulated enemy using UAVs and electronic warfare. The main force was the British 16th Air Assault Brigade, Britain's main rapid reaction unit. Germany provided logistics. About 600 paratroopers landed in several waves from four A400M Atlas aircraft of the Royal Air Force. Equipment and supplies were moved along with people. The 3rd Battalion of the British Parachute Regiment and a company of the 3rd Marine Battalion of France also participated in the exercise. Three Chinook helicopters supported the operation and delivered a medical aid station.
