The 7th Infantry Brigade and Headquarters East is a formation in the British Army with a direct lineage to 7th Armoured Brigade and a history that stretches back to the Napoleonic Wars. It saw active service in the Crimean War, the Second Boer War and both the First and the Second World Wars. In 2014, the 7th Armoured Brigade was re-designated as 7th Infantry Brigade, thereby ensuring that the famed "Desert Rats" continue in the British Army's Order of battle. 7th Infantry Brigade is also regionally aligned with the western African region as part of defence engagement.
