Introducing project “Military Insignia”, featuring top quality military heraldry designs. Here you will find designer apparel, accessories, custom postage and gifts decorated with insignia of the 33d Infantry Brigade Combat Team (33 IBCT). As part of the Army's transformation towards a modular force, in 2005, the title and composition of the 66th Infantry Brigade was changed to the 33d Infantry Brigade. The 33rd Brigade is one of the maneuver brigades of the 35th Infantry Division (Mechanized), headquartered at Fort Leavenworth, KS. The Brigade, with a total personnel strength of approximately 3,500 soldiers, has units located throughout Illinois. A light air assault unit, the brigade serves as the spearhead for the heavier mechanized infantry division. As an air assault brigade, it has few wheeled vehicles and relies on aircraft for mobility.
