The 28th Infantry Division ("Keystone") is a unit of the Army National Guard and is the oldest division-sized unit in the Department of Defense. Some of the units of the division can trace their lineage to Benjamin Franklin's battalion, The Pennsylvania Associators (1747–1777). The division was officially established in 1879 and was later redesignated as the 28th Division in 1917, after the entry of America into the First World War. It is today part of the Pennsylvania Army National Guard, Maryland Army National Guard, Ohio Army National Guard, and New Jersey Army National Guard. It was originally nicknamed the "Keystone Division," as it was formed from units of the Pennsylvania Army National Guard; Pennsylvania being known as the "Keystone State." During World War II, it was given the nickname the "Bloody Bucket" division by German forces due to the shape and color of its red keystone insignia. Today the 28th Infantry Division goes by the name given to it by General Pershing during World War I: "Iron Division." The 28th is the first Army National Guard division to field the Stryker infantry fighting vehicle, as part of the Army's reorganization in the first decade of the 2000s. The 28th is also one of the most decorated infantry divisions in the United States Army. Creation On 12 March 1879, Governor Henry Hoyt signed General Order Number One appointing Maj. Gen. John F. Hartranft as the first Division commander of the National Guard of Pennsylvania. Pennsylvania was the first state to structure its National Guard units at such a high tactical level in peacetime. From 11 to 18 August 1894, Camp Samuel W. Crawford was the "Division Encampment at Gettysburg". The division was mustered into federal service for the Spanish–American War in 1898. Pennsylvania initially levied 10,800 men, in ten infantry regiments and four artillery batteries. The entire division was mustered into federal service between 6 May and 22 July, and while 8,900 men had assembled at Mount Gretna for the muster parade on 28 April 1898, there was no difficulty in raising 12,000 men for service in two and a half months. However, only the 4th, 10th, and 16th Regiments, three artillery batteries, and three cavalry troops were deployed, to Puerto Rico. The 10th Regiment was then sent to the Philippines, being ordered home on 30 June 1899. The division was called up to respond to labor disturbances in 1877 and
