The 6th Infantry Regiment on Parade, c. 1905.

Mounted infantry officers had the regimental number in enameled leather on the rear corners of their dark-blue saddlecloths. These officers are in dress coats (not the full-dress double-brested coats). The front officer may be the regimental or battalion commander, and the officer behind him his adjutant. The men in the background appear to be in the pre-1902 coats with white shirt collars protruding prominently. Behind the commanding officer one can even make out the big drum of the regimental band.
