The majority of the command were rather young in years, although a few were of middle age. But all were tough and hardy, either from athletic training or from years spent in the open air of the great West. Some of them could ride almost any kind of a horse, and "bronco busting," that is, breaking in a wild steed, was common sport among them. Some had spent nearly their entire lives in the saddle, and some could exhibit remarkable skill with their firearms while riding at full speed.
