The 1st Infantry Division of the United States Army is the oldest division in the United States Army.[2][3] It has seen continuous service since its organization in 1917.[2] It was officially nicknamed the The Big Red One after its shoulder patch[2] and is also nicknamed The Fighting First.[2] However, the division has also received troop monikers of The Big Dead One and The Bloody First as puns on the respective officially-sanctioned nicknames.[4] It is currently based at Fort Riley, Kansas.
