I had a great-uncle (may God rest his soul) that was stationed in Burma during WWII where he worked with and got to know a lot of Gurkhas. He even had one to give him a Kukri blade. He used to say they were some of the kindest, most honorable people on Earth. But they were not to be trifled with-at all. He was glad they were on our side.
I saw an interview on TV back when Britain still controlled Hong Kong. A British officer there who commanded Gurkha guards or maybe troops really liked them.
He said they were pleasant with their own but deadly with their enemies.
