During WWII they took their training near my house at Camp Swift near Bastrop Texas. The land is flat and the weather is hot, typical Army planning
There is a book written by a surgeon with the 10th called Mountain Troops and Medics, Wartime Stories of a frontline surgeon in the US Ski Troops by Albert H. Meinke Jr. MD I bought the book in 1993 and read it but it was just OK , not really great reading. The guy had a fixation on how different people in different countries used the bathroom !
