and middle ranks of the new Iraqi officer corps, with senior commands being manned by British officers, as well as most training positions. The Musa al-Kadhim Brigade consisted of ex-Iraqi-Ottoman officers, whose barracks were located in Kadhimyah. The United Kingdom provided support and training to the Iraqi Army and the Iraqi Air Force through a small military mission based in Baghdad; providing weapons and training to defeat the anticipated Turkish invasion of northern Iraq. Royal Iraqi Army In August 1921, the British installed Hashemite King Faisal I as the client ruler of Mandatory Iraq. Faisal had been forced out as the King of Syria by the French in the aftermath of the Franco-Syrian War in 1920. Likewise, British authorities selected Sunni Arab elites from the region for appointments to government and ministry offices in Iraq. The British and the Iraqis formalized the relationship between the two nations with the Anglo-Iraqi Treaty of 1922. With Faisal's ascension to the throne, the Iraqi Army became the Royal Iraqi Army (RIrA). In 1922, the army totalled 3,618 men. This was well below the 6,000 men requested by the Iraqi monarchy and even less than the limit set by the British of 4,500. Unattractive salaries hindered early recruiting efforts. At this time, the United Kingdom maintained the right to levy local forces like the British-officered Iraq Levies which were under direct British control. With a strength of 4,984 men, the Iraq Levies outnumbered the army. In 1924, the army grew to 5,772 men and, by the following year, had grown even more to reach 7,500 men - maintaining this size until 1933. The force's order of battle consisted of: Six infantry battalions, Three cavalry regiments, Two mountain regiments, One field artillery battery. By the late 1920s, the threat of Turkish attack diminished, with the Iraqi army refocusing on new, internal missions. While the British command still worried about both Turkish and Persian encroachment on the Iraqi territory - as both of these states were considerably more cohesive and with superior armies -, the new focus shifted towards internal security against centrifugal forces menacing to breakdown the country. Those threats to the integrity of the nascent Iraqi state were separatist revolts by the Kurds and by the powerful tribes of western and southern Iraq. The British concluded the Iraqi army was not capable of handling either the Turks or the Persians, with the RAF (supported
