I think Gorkha refers to Durban (home security) only part of fun in India. Gorkha does not refer to indian Army. If you ask any Indian, they will say there are only two brave Regiments in Indian which #1 as Gorkha Regiment and #2. Punjabi Regiments.
      Those Durban which falsely refer as Gorkha is way different than Gorkha (Indian Army).
