'Buster' (ii) was a British unrealised plan by General Sir Claude Auchinleck’s 8^th Army to make a stand at El Alamein on the north-western border of Egypt with Italian-held Libya, and then to drive the Axis forces of Generalfeldmarschall Erwin Rommel’s Panzerarmee 'Afrika' back to the Tripoli region of Libya (July 1942).

The plan was overtaken by the Axis offensive which followed 'Aïda' and led to the Battle of Alam el Halfa and thence to the 1^st Battle of El Alamein.
