I think the uniform is most probably First World War, but I wonder if it could be from the Spanish-American War. See these images:

That appears to me to be a 1914 or 1917 US Army Uniform.
Which means it could be from US involvement in Mexico..
1913-1914. - U.S. troops carried out a skirmish against Huerta's forces in Veracruz.
March 1916 – February 1917 - Brig. Gen. John J. Pershing's expedition of about 10,000 soldiers went into Mexico trying to capture Pancho Villa after he raided into the US. They spent 11 months unsuccessfully chasing him.
April 6, 1917 - November 11, 1918. and WWI of course
1918–1919. Minor clashes with Mexican irregulars, as well as Mexican Federales near Nogalas Az.
