bombers, but both had been lost by the end of January 1918. 1920s & 1930s In 1919 the squadron was sent to Iran as part of the Norperforce. In April 1919, the squadron was reduced to a cadre at Baghdad, but not disbanded, and in February 1920, it returned to full strength at Baghdad as an Army co-operation squadron equipped with RE.8s, with these gradually being replaced by Airco DH.9A light bombers, with re-equipment being complete by early 1921. From June 1920, the squadron, along with the rest of the RAF's strength in Iraq, was deployed against an Iraqi revolt against British rule. In May–June 1921, 30 and 47 Squadron's DH.9As supported the establishing of a permanent Cairo–Baghdad land route, providing an air escort for vehicle convoys creating a visible track across the desert, while from 21 June that year the two squadrons began air-mail runs along the Cairo-Baghdad route. In early 1924, aircraft from the squadron were deployed to Kirkuk for operations against a revolt led by the Kurdish leader Sheikh Mahmud Barzanji. The city of Sulaymaniyah, the base of Mahmud's operations was bombed, and Mahmud withdrew into the mountains. The squadron again saw action in the summers of 1925 and 1926 as Mahmud's rebellion reignited, attacking rebel-held villages. In late February 1938, a flight of 30 Squadron aircraft joined 'Akforce', a force of aircraft set up to stop Ikhwan nomadic raiders from Saudi Arabia attacking Iraq and Kuwait, these operations continuing until June. In 1929 the squadron replaced its DH.9As with Westland Wapitis. In September 1930, Mahmud again raised a rebellion against the British and Iraqis, and 30 Squadron supported Iraqi Army operations against the rebels. The campaign against Mahmud continued until May 1931, when Mahmud surrendered. Wapitis of 30 Squadron flew 2204 hours between October 1930 and May 1931 in operations against Mahmud. In March 1932, the Iraqi Army launched an offensive against a revolt by the supporters of Ahmed Barzani in Southern Kurdistan. 30 Squadron initially provided reconnaissance support to the Iraqi Army columns, but after one column was heavily attacked and forced to retreat, the RAF launched a series of air attacks against Barzani's forces until Barzani crossed the border into Turkey. In April–August 1935 the squadron received Hawker Hardys (a tropicalised, general purpose version of the Hawker Hart light bomber), being the first squadron to receive the Hardy. In 1936 the squadron moved to
