Ever heard of a Gurkha? Gurkhas are best known for their history in the Indian Army's Gorkha regiments, the British Army's Brigade of Gurkhas and the Nepalese Army. Former Chief of staff of the Indian Army, Field Marshal Sam Manekshaw, once famously said about Gurkhas:
'I had so many of them around me that I thought I was definitely going to die so I thought I'd kill as many of them as I could before they killed me.
Most of the militants were about 50ft away from him, but at one point he turned around to see a 'huge' Taliban fighter looming over him.
The soldier picked up his machine gun and fired a long burst at the man until he fell off the roof.
When another insurgent tried to climb up to his position, the Gurkha attempted to shoot him with his SA80 rifle. But it did not work, either because it had jammed or because the magazine was empty.
He first grabbed a sandbag but it had not been tied up and the contents fell to the floor.
Then he seized the metal tripod of his machine gun and threw it at the approaching Taliban militant, shouting in Nepali 'Marchu talai' ('I will kill you') and knocking him down.
