The Alzola brothers each had talents that complemented the others'.  Working with horses and mules, especially breaking and training them, became Frosty's specialty.  He was working on a cattle ranch in Battle Mountain, Nevada when he received his draft notice to fight in World War II.  Frosty served in the 699 Remount Service of the US Army, breaking horses, mules, and donkeys in Burma for use by officers and artillery divisions.  In Burma and India Frosty hunted elephants, tigers, and leopards upon request by villagers, played polo against the British Army, and participated against some of the first rodeos outside the United States.

After five years in the service, Frosty returned to Mountain Home to help his brothers sell the Bruneau Sheep Company and move to the TM Ranch in Nevada.  He enjoyed working with children who came from all over the United States to learn about horses and life on a ranch.  Fifty years later, Frosty retired after a lifetime in the saddle.
