Sgt.D, most scabards I've seen were covered in some DPM tape bought from the NAFFI. I've seen some with cloth from an old combat jacket just glued on. Recently, with the new combat '95 webbing system, I've seen some cordura sheaths.
www.sass-kit.fsbusiness.co.uk has DPM covers which may be even the ones on issue??
Training, other than normal combat training I'm not entirely sure of. There must be some in house stuff if only to stop those who were not brought up with kukris damaging themselves.
There is not much to the Gurkha secret. Take a young man from the hills, bring him up to speed on European weapon systems under the best and most intelligent leadership you have. (This includes some sound education and a good dollop of tradition). Coop him up doing some guard duty at Buckingham Palace, or demonstrating "how it should be done" on the hills of Wales (cold and wet) and in the jungles of Belize (hot and wet). Then when you do have an enemy, just let'em at'em under control to do their job. When the bullets and bombs have run out, (which Gurkha's are very adept at using), they have a kukri to cleave off any remaining offending limbs and heads. All this and still smiling. The Gurkha: a very up to date and efficient mercenary fighting system.
Lasty, the British Army has training pamphlets on most things. The cavalry can still be tought how to use a lance. I am sure the Gurkha's do have a basic course for kukri use. However, like most things in the British Army, more advanced stuff is done by those who want to do it and there are those who can teach it. There is time in the training programme for it. My thoughts are that in the case of a Kukri, which is a bludgeon weapon, a fighting cleaver, there is probably not that much to it other than be fit, agile and coordinated enough to work it fast. Gurkha's are fit, agile and coordinated.
