The Gurkhas also spelled as Gorkhas, are soldiers from the South Asian country of Nepal. Historically, the terms "Gurkha" and "Gorkhali" were synonymous with "Nepali," and derived from the hill town and district of Gorkha from which the Kingdom of Nepal expanded.Legend has it that the name may be traced to the medieval Hindu warrior-saint Guru Gorakhnath who has a historic shrine in Gorkha. Gurkhas are traditionally recruited from various Nepali hill ethnicities, but do not come from a single group or region in the multi-ethnic country.
Gurkhas are closely associated with the Khukuri, a forward-curving Nepalese knife and have a well known reputation for their fearless military prowess. http://en.wikipedia.org/wiki/Gurkha
