The deal will see the car company help stage the event, which aims to use sport to inspire recovery and rehabilitation of members of the armed forces who have been injured in the line of duty, the 'Telegraph' reported.
As well as providing the financial clout to help stage the event, which will see 400 competitors from the militaries of 14 countries competing at sporting disciplines, Jaguar Land Rover is also organising a driving competition for servicemen at its research and test base.
Prince Harry was driven to launch the games following a visit last year to America's Warrior Games for injured US servicemen.
