Exercise Rhino Titan took place at the Sennelager military training area and involved roughly 2,500 personnel.
A total of 600 paratroopers from the United Kingdom's 16 Air Assault Brigade and French forces dropped from four RAF A400M Atlas aircraft.
British officials stated the drills were designed to test the ability to defend NATO territory against an adversary using modern tactics, including electronic warfare systems and drone swarms, capabilities widely associated with Russia's military.
Brigadier Ed Cartwright, commander of 16 Air Assault Brigade, said troops were "pitted against an enemy using drones and electronic warfare, which is what we would face on the modern battlefield."
Defence Secretary Wes Streeting said the threats of the 21st century require an "updated, modern approach to warfare – and our adaptable armed forces are preparing accordingly." He added that the exercise shows the UK and its allies "can deliver rapid, large-scale airborne power anywhere it's needed to defend Nato territory" and that the combination of troops and equipment is "what is required to deter our adversaries and keep Britain and our allies safe."
The joint exercise comes amid European fears of Russian hybrid attacks, including arson and sabotage, as the war in Ukraine continues.
