Campaign hat

A campaign hat (also campaign cover, drill instructor cover, drill sergeant hat, lemon squeezer, Montana Peak, Mountie hat, ranger hat, sergeant hat, Scouts hat and Smokey Bear) is a broad-brimmed felt or straw hat, with a high crown, pinched symmetrically at the four corners (the "Montana crease").

It is associated with the New Zealand Army, the Royal Canadian Mounted Police, the World War I ground forces of the United States Army, contemporary U.S. military drill instructors, state police forces, park rangers and forest rangers (and from them, their logo-cartoon and mascot Smokey Bear), Boy Scouts, and others.

Although the campaign hat is occasionally referred to as a Stetson, this is from its common manufacture in the late 19th century by that company. It should not be confused with the quite different Stetson hat type with a different brim and crease, commonly known as the cowboy hat, and which is more commonly meant by the term "Stetson" today. The campaign hat also should not be confused with a slouch hat.
