My father was a part of this group, they were actually called SACO. He liked this movie, thought it was somewhat accurate. He was a Navy Chief Petty Officer, a Medic, he loved Mongolia, it reminded him of Montana, where he grew up, and he admired the people. He liked the humor in it. They were actually a sort of obscure, almost "guerilla" group. Kind of like Navy Calvary. I thought it was called "Saddles for SACO", (maybe another earlier title?). He always felt it was a great mistake to underestimate the indigenous people, he used to use Mr.Custer as an example. All the West Point training or Annapolis , for that , purpose , may not help you in the end.And he told me, all Americans think they're John Wayne, unfortunately, those ponies didn't always know.
