Gurkha word itself derived from "Go-Raksha" (), "raksha" becoming "rakha" (रखा). "Rakhawala" means "protector" and is derived from "raksha" as well. There are Gurkha military units in the Nepalese, British and Indian armies enlisted in Nepal, United Kingdom and India. Although they meet many of the requirements of Article 47 of Protocol I of the Geneva Conventions regarding mercenaries, they are exempt under clauses similarly to the French Foreign Legion. Gurkhas are closely associated with the khukuri, a forward-curving Nepali knife, and have a reputation for fearless military prowess. Former Indian Army Chief of Staff Field Marshal Sam Manekshaw once stated
Gurkha that: "If a man says he is not afraid of dying, he is either lying or he is a Gurkha." During the Anglo-Nepalese War (1814–16) between the Gorkha Kingdom (present-day Federal Democratic Republic of Nepal) and the East India Company, the Gorkhali soldiers made an impression on the British, who called them "Gurkhas". The Anglo-Nepalese war was fought between the Gurkha Kingdom of Nepal and the British East India Company as a result of border disputes and ambitious expansionism of both the belligerent parties. The war ended with the signing of the Treaty of Sugauli in 1816. David Ochterlony and
