He understood that he was totally encompassed and that the Taliban were going to dispatch an all around arranged endeavor to overwhelm the compound.
The foe opened flame from all sides, annihilating the sentry position where Acting Sgt Pun had been on obligation minutes prior.
Safeguarding the base from the rooftop, the Gurkha stayed under constant assault from rocket-pushed projectiles and AK47s for over quarter of 60 minutes.
The vast majority of the aggressors were around 50ft far from him, however at one point he pivoted to see a "colossal" Taliban warrior approaching over him.
Acting Sgt Pun got his automatic rifle and shot a long burst at the man until he tumbled off the rooftop.
At the point when another guerilla attempted to scale to his position, the Gurkha endeavored to shoot him with his SA80 rifle.
