The United States Cavalry, or U.S. Cavalry, was the designation of the mounted force of the United States Army by an act of Congress on 3 August 1861. This act converted the U.S. Army's two regiments of dragoons, one regiment of mounted riflemen, and two regiments of cavalry into one branch of service. The cavalry branch transitioned to the Armored Forces with tanks in 1940, but the term "cavalry", e.g. "armored cavalry", remains in use in the U.S. Army for mounted reconnaissance, surveillance, and target acquisition (RSTA) units based on their parent Combat Arms Regimental System (CARS) regiment. Cavalry is also used in the name of the 1st Cavalry Division for heraldic/lineage/historical purposes. Some combined arms battalions are designated as armor formations, while others are designated as infantry organizations. These "branch" designations are again, heraldic/lineage/historical titles derived from the CARS regiments to which the battalions are assigned.
The 2nd Cavalry Division was a cavalry division of the United States Army.
The Massachusetts National Guard is the National Guard component for the Commonwealth of Massachusetts. Founded as the Massachusetts Bay Colonial Militia on December 13, 1636, it contains the oldest units in the United States Army.

Originally founded as a defensive militia for Puritan colonists in the Massachusetts Bay Colony, the militia evolved into a highly organized and armed fighting force. The Massachusetts militia served as a central organ of the New England revolutionary fighting force during the early American Revolution and a major component in the Continental Army under George Washington.
The Wisconsin Army National Guard ("Guard") has dual state and federal roles, and is jointly funded and maintained by both governments. Its federal mission is to provide trained units to the United States Army in time of war or national emergency. Its state mission is to help civil authorities protect life and property and preserve peace, order, and public safety in times of natural or human-caused emergencies. The governor, who is the commander in chief of the Guard when it is not activated for federal service, appoints the adjutant general who directs the Wisconsin Department of Military Affairs, of which the Guard is a part. Members of the National Guard are typically part-time soldiers who attend unit drills one weekend per month and serve a two-week annual tour of active duty. All officers and enlisted personnel must meet the same physical, education, and other eligibility requirements as members of the active-duty services.

This list of United States Army divisions is divided into three eras: 1911–1917, 1917–1941, and 1941–present. These eras represent the major evolutions of army division structure. The 1911–1917 era lists divisions raised during the Army's first attempts at modernizing the division, prior to the authorization of permanent divisions, and the 1917–1941 era lists the first permanent divisions, prior to advent of specialized divisions. The 1941–present era lists all of the divisions organized, raised, or authorized since then.

The history of the United States Army began in 1775. From its formation, the United States Army has been the primary land based part of the United States Armed Forces. The Army's main responsibility has been in fighting land battles and military occupation. The Corps of Engineers also has a major role in controlling rivers inside the United States. The Continental Army was founded in response to a need for professional soldiers in the American Revolutionary War to fight the invading British Army. Until the 1940s, the Army was relatively small in peacetime. In 1947, the Air Force became completely independent of the Army Air Forces. The Army was under the control of the War Department until 1947, and since then the Defense Department. The U.S. Army fought the Indian Wars of the 1790s, the War of 1812 (1812–15), American Civil War (1861–65), Spanish–American War (1898), World War I (1917–18), World War II (1941–45), Korean War (1950–53) and Vietnam War (1965–71). Following the Cold War's end in 1991, Army has focused primarily on Western Asia, and also took part in the 1991 Gulf War and war in Iraq, and the war in Afghanistan.
The Kentucky Army National Guard is a component of the United States Army and the United States National Guard.

National coordination of various state National Guard units are maintained through the National Guard Bureau.
Twenty-four current units of the Army National Guard perpetuate the lineages of militia units mustered into federal service during the War of 1812. Militia units from nine states that were part of the Union by the end of the War of 1812, plus the District of Columbia, are the predecessors of eighteen units that currently exist in the Army National Guard. Two of the four units derived from Virginia militias are in the West Virginia National Guard; at the time of the War of 1812, West Virginia was still part of Virginia. Only two current units, the 155th Infantry, a component of the Mississippi National Guard derived from militia units organized in the Mississippi Territory and the 130th Infantry, a component of the Illinois National Guard derived from militia units formed in the Illinois Territory, are from states or territories west of the Appalachians. Unfortunately, no militia units from the states of Kentucky, Louisiana, Ohio or Tennessee, or from the Indiana, Michigan, Missouri or Louisiana Territories, where militia units played a major role in the fighting, have survived as units in the modern Army National Guard.
