The 1st Mechanized Infantry Brigade (German: Panzergrenadierbrigade 1) in Hildesheim was a formation in the Bundeswehr, which was subordinated to the 1st Armoured Division in Hanover. The Brigade was disbanded on 31 December 2007. During its lifetime the Brigade was stationed between the Lüneburg Heath, Harz Mountains, the Solling hills and the River Weser.
The formation sign displays the white Sachsenross or Saxon steed on a red background within a yellow and white shield. The steed recalls the Welf dukes and the Kingdom of Hanover. The original Saxon tribal emblem was adopted in 1235 by the Welf dukes, the Dukes of Brunswick and Lüneburg, as an additional coat of arms. Through the amalgamation of part of the Lüneburg-Brunswick region with the Principality, later Kingdom, of Hanover the Saxon steed appeared in 1705 on the escutcheon of the kingdom's coat of arms surrounded by the main yellow and white shield. On the foundation of the state of Lower Saxony in 1952 the Saxon steed on a red field became the coat of arms of the state. The white border of the coat of arms, in embroidery shown as a white cord - represents the usual heraldic custom of the German Army: white borders were always the formation signs of the "first" brigades in a division. The superior division as well as the other two brigades in the division traditionally bore an identical formation sign apart from the white border. On the disbandment of the Brigade the sign continued to be worn by Panzerlehrbrigade 9, which gave up its old sign in 2006. The white border remains.
In 2007, just before disbanding the brigade was organised as:
