A Nepalese Gurkha took his responsibility of positively identifying a high value Taliban commander extremely seriously. He went as far as using his tradition kukri to kill the commander, remove his head and brought it back to base.
According to the Daily Mail:
A Gurkha solider who beheaded a Taliban gunman and carried his head back to base in a bag has been cleared to resume his duties.
The private, from 1st Battalion, Royal Gurkha Rifles, was involved in a fierce firefight with insurgents in the Babaji area of central Helmand Province when the incident took place earlier last July.
The Nepalese soldier, who is in his early 20s, apparently made the decision to remove the head in a misunderstanding over the need for DNA evidence of the kill.
There was some debate as to whether the soldier would be allowed to return to duty as disfiguring the corpse of an enemy can sometimes be treated as a warcrime. However, it was found that the Gurkha waas out of ammunition and had to choice but to deploy the kukri.
According to Wikipedia, the legendary kukri is not a weapon to be underestimated.
The kukri is a Nepalese knife with an inwardly curved blade, similar to a machete, used as both a tool and as a weapon in Nepal and some neighbouring countries of South Asia. Traditionally it was, and in many cases still is, the basic utility knife of the Nepalese people. It is a characteristic weapon of the Nepalese Army, the Royal Gurkha Rifles of the British army, the Assam Rifles, and Gorkha Regiments (India) of the Indian Army, and of all Gurkha regiments throughout the world, so much so that some English-speakers refer to the weapon as a “Gurkha blade” or “Gurkha knife”. The khukuri often appears in Nepalese heraldry and is used in many traditional rituals such as wedding ceremonies.
Several years ago, a Gurkha returning home from service on a train used his trusty kukri to take on 40 criminals on a train and stop the rape of a young woman.
