In the aftermath of the June–September 1982 Israeli invasion of Lebanon, President Amin Gemayel, convinced that a strong and unified national defense force was a prerequisite to rebuilding the nation, announced plans to raise a 60,000-man army organized into twelve brigades (created from existing infantry regiments), trained and equipped by France and the United States. In late 1982, the 4th Infantry Regiment was therefore re-organized and expanded to a brigade group numbering 2,000 men, most of whom were Maronite Christians from the Mount Lebanon region and Druzes from the Chouf District, which became in January 1983 the 4th Infantry Brigade.
