Armored brigade combat team in the context of Brigade (United States Army)

The Stryker is a family of eight-wheeled armored fighting vehicles derived from the Canadian LAV III. Stryker vehicles are produced by General Dynamics Land Systems-Canada (GDLS-C) for the United States Army in a plant in London, Ontario. It has four-wheel drive (8×4) and can be switched to all-wheel drive (8×8).

The Stryker was conceived as a family of vehicles forming the backbone of a new medium-weight brigade combat team (BCT) that was to strike a balance between armored brigade combat teams (heavy armor) and infantry brigade combat teams. The service launched the Interim Armored Vehicle competition, and in 2000, the service selected the LAV III proposed by GDLS and General Motors Defense. The service named this family of vehicles the "Stryker".

The 1st Cavalry Division ("First Team") is a combined arms division and is one of the most decorated combat divisions of the United States Army. It is based at Fort Hood, Texas. It was formed in 1921 and served during World War II, the Korean War, the Vietnam War, the Persian Gulf War, with the Stabilization Force in Bosnia and Herzegovina, the Iraq War, the War in Afghanistan as well as Operation Freedom's Sentinel and Operation Inherent Resolve. As of July 2023, the 1st Cavalry Division is subordinate to the III Armored Corps and is commanded by Major General Thomas M. Feltey.

The unit is unique in that it has served as a cavalry division, an infantry division, an air assault division and an armored division during its existence.

The 1st Infantry Division (1ID) is a combined arms division of the United States Army, and is the oldest continuously serving division in the Regular Army. It has seen continuous service since its organization in 1917 during World War I. It was officially nicknamed "The Big Red One" (abbreviated "BRO") after its shoulder patch and is also nicknamed "The Fighting First". The division has also received troop monikers of "The Big Dead One" and "The Bloody First" as puns on the respective officially sanctioned nicknames. It is currently based at Fort Riley, Kansas.

The 1st Infantry Division was first deployed to fight in France in World War I, fought extensively in Africa, Italy, France, and Germany during World War II, and participated extensively during United States' campaigns in the Vietnam War. The 1st Infantry was stationed in what became West Germany from 1945 to 1955, and its units rotated to West Germany throughout the remainder of the Cold War. It subsequently deployed to fight in the Gulf War, the Iraq War, and the War in Afghanistan. 37 members of the "Big Red One" have been awarded the Medal of Honor, making the 1st Infantry one of the U.S. Army's most honored divisions [1].
