I assume that this took place in Nepal.
No one messes with the Gurkhas. I recall I was in Punta Gorda, Belize in 1980, and there were a number of troops there to protect Belize, which was about to become independent, from possible problems with Guatemala, which has never ceased to claim all of Belize as part of Guatemala. In 1823 or so, the president of Guatemala made a deal with the Brits to let them log mahogany in Belize (with slaves from Jamaica) in return for the Brits building a road from Guatemala City to the port at Puerto Barrios. They gave el presidente the money to build the road, and he absconded with the money and lived happily ever after in Paris. So the Brits figured that they had kept their end of the bargain, and took over the place, which was only inhabited by Indians, which in those days did not count. Indians in Guatemala in 1980 did not count, either, by the way. In Punta Gorda, Belize, there were Maya Indians all of whom spoke Spanish and were therefore called "Ladinos", "Coolies", who were East Indians, some Chinese, and a majority of Black Belizeans, who spoke a sort of Jamaican-like patois that was not too hard to understand
In any case, there were three groups of soldiers: British, Scots (called "Jocks" by the Brits) and Gurkhas. The Brits and the Scots had their favorite off duty bars and hung out there. The Gurkhas stayed in their barracks and apparently spent a lot of time polishing shoes and brass, because there were no shiny things in Punta Gorda other than the Gurkhas: the shoes, the knife scabbards, etc. Gurkhas all went out of their ways to look alike: they all looked like twins: Nepalese Umpa-Lumpas. The Scots and the Brits, on the other hand, did all the could to look different, tattoos being their favorite way of doing this. There were two tattoo parlors in Punta Gorda, which had officially, under 2,000 people, I assume not counting soldiers.
The Brits and the Scots and everyone else agreed: the Gurkhas all kept to themselves, and no one messed with a Gurkha. Messing with Gurkha would cause one to have all the Gurkhas against them: the Gurkhas, would tell their commander, and the Gurkha commander would issue a complaint to the British or Scottish commander, and the offending Brit or Scot would be reprimanded , and no commanding officer would be likely to believe that having a Gurkha complain about another soldier was the Fault of the Gurkha.
Most Nepalese are not from the same tribe as the Gurkhas. They are from only one group, and are chosen by very demanding standards.
In Haiti, the Nepalese have been accused of bringing cholera to Haiti, but I do not think the accused were Gurkhas. I can';t imagine why anyone would wish to bring cholera to any place. But the strain was identified as being an East Indian strain, and there are no people from anywhere near India in Haiti other than Nepalese.
