With a post '45 pod, have the US Army field a minimum of a brigade size formation of Gurkha's.
Regards filers.
That's going to be really tough. Basically, the Gurkhas have an affection for Britain that is astonishing, and Britain is always going to be their very first choice. The Indian Army (following Independence) also makes a lot of use of the Gurkhas, and the Gurkhas like this, because of the minimisation of the language and cultural differences.
It's certainly the case that in 1974-76, when I was in Nepal recruiting Gurkhas (one of the easiest tasks in the world), I don't think I ever heard one of them mention the United States in any way. It wasn't on their radar (which, given the state of the US Army in 1976 is probably just as well. 1976 was probably the nadir of the competence of the US Army).
For the Gurkha, ties of blood and salt and honour are important. They have that in spades with Britain, a shared history and tradition going back well over a century even then. America, to them, is just another place on the map.
To get a number of Gurkhas to want to join the US Army, you've first got to get rid of the possibility of Britain and India using them, which is going to be tough.
Then you've got the big problem that the Gurkha style is not a very good mesh with US Army doctrine. The US Army relies on a lot of very high-tech kit. The Gurkhas don't have the educational base to be entirely comfortable with high-tech kit. The US Army also has a doctrine that basically starts on the basis of dealing with a situation from a distance. The Gurkha is much more comfortable up close and personal (although the other party is seldom comfortable under such circumstances). US doctrine is just such a rubbish mesh with the skills of the Gurkha.
And that's before we get into cultural issues. You know the phrase: "He who fights and runs away lives to fight another day"? Guess what the Gurkha attitude to that is. The RGR motto: "Better to die than live a coward" is perhaps answer enough.
But the big problem you face is that with a post '45 POD, there isn't time to build up years of joint service and loyalty, and the Gurkha just wouldn't be interested.
