Re the Ghurkhas.
My old dad was a medical technologist in the British Medical corps in North Africa in WW2. His only spell of duty involving a firearm had him standing guard one night in a foxhole, holding a SMLE in his shaking hands.
At some point in the icy, silent desert night, a pair of dark hands appeared around his neck, felt for his dogtags, found them and withdrew. a soft voice said "Goodnight sahib"
and the gurkha was gone. His approach had not been heard. One of the hands had been holding a razor sharp Sykes Fairbairn commando knife right next to Dad's jugular.
Had he not been wearing British dogtags, Johnny Warner (Jack Halyard to you) would not have happened.
Dad always said "the colour of adreniline is brown."
I'm most glad those worthy lads were on our side. But yes, they come with the finest reputation history offers its soldiers.
