Did the Royal Navy have an equivalent of the Gurkhas as a contracted foreign force?
Short answerNot directly; it employed overseas personnel and the East India Company used sepoy marines, but no single tradition matched the Gurkhas.
NotesThere was no direct naval equivalent to the Gurkhas. Royal Navy ships had a long tradition of employing laundry personnel recruited in Hong Kong and elsewhere. The East India Company also fielded Indian sepoy marine formations. These examples show sustained overseas service without one institution carrying the same identity and continuity as the Gurkha regiments.
