The Army of Africa included indigenous
Arab or
Berber volunteers; (
spahis,
Goumiers and
tirailleurs); regiments largely made up of
pied-noir French settlers doing their military service (
zouaves and
chasseurs d'Afrique); and non-French volunteers (
Légion étrangère). The divisions were not absolute and (for example) volunteers or conscripts from mainland France might choose to serve with the
Muslim rank and file of the spahis and tirailleurs, while Arab volunteers might appear amongst the ranks of the zouaves. Prior to World War I, one battalion of each of the four zouave regiments then in existence, was recruited in France. These battalions' bases were thereby providing a framework that could be expanded in the event of general mobilisation, and which were physically located closer to the geographical threat of Germany. In addition to the corps listed above, the Army of Africa included technical and support branches - notably artillery, engineers and train. Stationed permanently in North Africa these comprised a mixture of French and indigenous personnel that varied according to recruitment availability. In May 1913 a limited form of selective conscription was applied to the Muslim population of Algeria. In theory, from this date, all young Muslim males were called to undertake three years of compulsory military service upon reaching the age of 18. However only about 2,000 conscripts a year were obtained by this method, out of approximately 45,000 possible candidates and Muslim enlistment remained predominately voluntary in peacetime. Even during World War I the majority (89,000 out of 170,000) of Muslim soldiers who served were volunteers. As in France itself, military service was an obligation of citizenship and all physically fit male settlers of French origin were required to undertake two years of compulsory service (three years from 1913). Officers of all branches of the Army of Africa were predominantly French Europeans, though a certain number of commissioned positions up to and including the rank of captain were reserved for Muslim personnel in the spahis and tirailleurs. In 1932 the proportion of
officiers indigenes was fixed at nine out of a total of 67 in each of these regiments. In 1956, in the course of the
Algerian War, a new policy of greater racial integration was adopted in the remaining units of the old Army of Africa. Algerian tirailleur regiments were to be made up of roughly 50% "Frenchmen of North African stock" (i.e. Arab and Berber Muslims) and an equivalent number of French volunteers and conscripts, largely drawn from the European settler community. At the same time, additional Muslim soldiers were to be incorporated into previously mostly European units such as the zouaves, until they made up to 25% of the total. Growing tensions within mixed units as the war continued, plus the threat of rebel
FLN reprisals against Muslim volunteers, largely nullified this attempted reform. Towards the end of the period of French rule in 1959 the personnel breakdown of a typical regiment of
tirailleurs Algerien had stabilised at about 60% Muslim and European volunteers, enlisted under contract (
engages); plus 20% European and 20% Muslim conscripts (
appeles). ==Formal status==
