 The 7th Battalion, Suffolk Regiment was a war-formed unit raised in June 1940, shortly after Dunkirk, and, on 10 October, was assigned to the 210th Independent Infantry Brigade (Home) alongside other hostilities-only battalions.With the brigade, the battalion alternated between home defence duties and training to repel an expected invasion of the United Kingdom.In November 1941, with the threat of invasion reduced due to the oncoming winter, the battalion was converted to a regiment in the Royal Armoured Corps, becoming 142nd Regiment Royal Armoured Corps (142 RAC) and joined 25th Army Tank Brigade.
