Prior to 1942, Jones' decoy tank force was somewhat informal, deployed as needed in deceptions. However, for the Battle of Alam el Halfa, at the end of August 1942, the decoys became 4th Armoured Brigade (a recently disbanded formation) and, mixed with real tanks, were given the task of harrying Rommel's flanks. During this time Jones, as commander of the Brigade, was briefly promoted to the rank of Brigadier (a rank which was removed following completion of the El Alamein campaign). In September 1942 Jones was appointed Officer of the Order of the British Empire. On 13 January 1944 he received a Mention in Despatches "in recognition of gallant and distinguished services in the Middle East". Jones retired from the army on 12 August 1948 and was granted the honorary rank of lieutenant colonel.
