The commonly used version of the motto of 3 Gorkha Rifles is "Kafar Bhanda Marnu Ramro"
However, there are several versions of the motto in Nepali. All of them mean the same "It is better to die in Valour than to live like a Coward"
The Official Motto is "KAFAR BHANDA MARNU JATI"
the other versions are:
KAFAR BHANDA MARNU RAMRO/JATI
KAFAR HUNNU BHANDA MARNU RAMRO/JATI
KAYAR BHANDA MARNU RAMRO/JATI
KAYAR HUNNU BHANDA MARNU RAMRO/JATI
The "Ramro" can be replaced with "Jati" which essentially means "traditional" or "befitting of ones caste"
Lt Col Jaideep Chanda provided this information on the motto.
