Traditionally, the Gurkhas have always been nails. During The Gurkha War, British soldiers were so impressed by their fighting ability, they got them on side as soon as possible afterwards. Ghurkas have served with distinction in every conflict we've fought for the last 200 years. They're a famously loyal, cheerful, fierce and hardy race of people.
Training and selection is tough... At the selection phase held in Nepal, there are 30 applicants for every available position in the Brigade of Gurkhas. Only the best of the best even get to attend basic training in Britain.
