While training in Waiouru on 13 February 1974, Sergeant Hudson was awarded a posthumous, George Cross for the following action. "While supervising a live grenade practice, Sergeant Hudson suddenly became aware that the NCO in his grenade throwing bay had accidentally armed the grenade he was about to throw. The Sergeant was then seen to quickly grasp the NCO’s throwing hand and attempt to throw the grenade over the front parapet of the throwing bay. He was within inches of success when the grenade exploded killing both men. Sergeant Hudson displayed devotion to duty and courage of a very high order when, with a complete disregard for his own safety, he attempted to save the life of a fellow soldier."
