Been away up to Scotland for some shooting.
Though my old Battalion (I'm out now), is affiliated with the Gurkha Regiments (light infantry and share several traditions and similar uniforms), I have only a passing knowledge of their traditions. Same infantry training, have been taught and taught them. So there is a limit to what I can add. (I'm not going to give out the whole British Army Infantry syllabus, so don't ask). However, I can tell you Gurkhas do produce the best curry in Wales from a ration pack.
Couple of points:
FNG, "poor individual small unit skills" My soldiers individual skills were very high, but to win a fire fight let alone a battle takes hours and loads of ammunition even when you do try to conserve it with fire control orders. Every rifleman knows how to put down a support fire mission because invariably its Rifleman Snotgrass who is in the best position to see where it should go.
Comparing different armies is always difficult as most have the good, bad and ugly. Cultural, and all that jazz adds to the confusion.
A general point. Most clan systems have jousting rules to prove a point without excessive deaths. Not unlike most Friday nights. The Gurkha village battles of yore, though brutish, did not entail too many fatalities. Deaths led to blood feuds that could last generations. This could be possibly one of the reasons long swords were not developed or carried to every fight. Nor an all out marial art for the kukri. Don't take this as gospel though.
Sorry, but most of my reference material is boxed up as I'm on the move. There is lots of Gurkha history out there in Military history book shops. General Slim and anything to do with the Chindits of WWII is good stuff.
Recently, they have been busy in Bosnia, Kosovo, Siere Lione, and Indonesia. Frankly, they have been working flat out in the last couple of years.
