We were given exclusive access to one of the biggest military exercises to have taken place in the world this year.

Forces News followed the Welsh Cavalry on Exercise Rattlesnake, in the United States.

The exercise, which takes place at the US Army Training Centre in Louisiana, is designed to test troops to their limits.
