27th Infantry Regiment, c. 1910.
Company G of the 27th Infantry has a group photograph taken in their full dress uniforms. Between 1902, the year these uniforms were introduced, and the start of World War I when they were discontinued, the 27th Infantry had two periods stationed within the United States—1904-06 and 1909-15. Both periods were at Fort Sheridan, Illinois, so it is highly likely that this is the location of this photograph.
