Arab Army Primary Reserve

The Arab Army Primary Reserve (Arabic: احتياطي الجيش العربي الأوّل aḥtiyāṭī al-jaysh al-‘arabī al-awwal) is the main reserve component of the Arab Army, the land warfare branch of the Arab Union's military, the Union Defence Forces. The Primary Reserve has an estimated total of 1.88 million personnel, making it one of the world's largest reserve forces. Its members are the most highly trained of the three currently operational army reserve components of the Arab Union, and the first to be called upon to active duty in event the Arab Army requires additional manpower. Of the nearly 2.9 million army reservists in the Arab Union, 1.88 are enrolled in the Primary Reserve, with the remaining 1.1 million are split roughly evenly between the Secondary Reserve and the Tertiary Reserve (approximately 550,000 each).
