Arab Army Tertiary Reserve

The Arab Army Tertiary Reserve (Arabic: احتياطي الجيش العربي الثالث aḥtiyāṭī al-jaysh al-‘arabī ath-thālith) is the third, smallest and most basically trained of the three official reserve components of the Arab Army, the land warfare branch and largest service branch of the Union Defence Forces, the military of the Arab Union. Members of the Tertiary Reserve are only called upon for active duty after the Primary Reserve and Secondary Reserve have been exhausted of their members and the Arab Army requires yet more servicemembers. As of 2021, the Tertiary Reserve has an estimated 520,000 members.
