About ten years ago, as a civ senior lecturer at Cranwell myself and a colleague went out to the Nigerian academy in Kaduna. We went in our old uniforms ( got permission from Innsworth) We gave their instructors a week of Radar. At the end, the Gp Capt thanked us, turned to his instructors and said "now you see how it is done", burst into tears and said that his time at Locking had been the best training in his life.
