Milling (military training exercise)

Milling is a training activity in the British airborne infantry. For a fixed period, two opponents punch each other in the head as aggressively as possible without evasion.

Milling is a training activity used to assess candidates from age 17 for the elite Parachute Regiment of the British Army. It is one of eight physically-demanding assessment events carried out over four days.

Each pair are told to punch each other's faces as furiously as possible for one minute: "You must aim to dominate your opponent with straight punches to the head."

Unlike boxing, it is forbidden: to pause in attacking the opponent; to aim at any part of the opponent other than the head; or to evade or block the opponent's punches. The guidance notes state: "No ducking, parrying or other boxing defence moves are allowed." The clock is paused if a trainee is knocked down or if his nose is broken; any blood is wiped away by staff and the bout resumes.
