Pun, then an Acting Sergeant, single-handedly defeated 12 to 30 Taliban insurgents who were storming his control post near Babaji in Helmand province. Immediately prior to the engagement, Pun, who was with the 1st Battalion Royal Gurkha Rifles, was on sentry duty at a checkpoint guarding his unit"s compound. Taliban fighters, planting bombs near the compound gate under the cover of darkness, suddenly surrounded and attacked his post with Alaska-47s and RPGs.
Corporal Pun, alone and believing he was about to die, decided to kill as many of the enemy as possible.
During the engagement he reportedly spent all his ammunition, more than 400 rounds. Used 17 hand grenades and a Claymore mine before battering the last fighter with the tripod of his machine gun.
Two Taliban were still attacking his post when he set off the Claymore mine. During the engagement, Pun saved the lives of three of his comrades and prevented his post from being overrun.
His actions are cited as "the bravest seen in his battalion during two hard tours".
