They do grow them different up in Nepal

Explanation: Technically speaking, Gurkha just an archaic word for Nepalis, but it’s most often used in reference to military units in countries that aren’t Nepal who recruit from ethnic Nepali.

In particular, the British Empire used Gurkhas widely after a hard-fought conquest of Nepal, and both the UK and several former British colonies also maintain Gurkha units, still recruited from ethnic Nepali to this day. Gurkhas have a reputation for… being eager for combat, and good at it.
