Modern Ranger Battalions
After the Vietnam conflict, division and brigade commanders determined that the U.S. Army needed elite, rapidly deployable light infantry, so in 1974 General Creighton Abrams constituted the 1st Ranger Battalion; eight months later, the 2nd Ranger Battalion was constituted, and in 1984 the 3rd Ranger Battalion and their regimental headquarters were created. In 1986, the 75th Ranger Regiment was formed and their military lineage formally authorized. The 75th Ranger Regiment, comprising three battalions, is the premier light-infantry of the U.S. Army. It is a flexible, highly trained and rapid light infantry specialized to be employed against many conventional and special operations targets. The 4th, 5th, and 6th Ranger Battalions were re-activated as the Ranger Training Brigade, the cadre of instructors of the contemporary Ranger School; moreover, because they are parts of a TRADOC school, the 4th, 5th, and 6th battalions are not formally included to the active strength of the 75th Ranger Regiment.
The Rangers have participated in the following operations: the 1980 rescue attempt of American hostages, Tehran, Iran in (Operation Eagle Claw); the 1st and 2nd Ranger Battalions in Operation Urgent Fury on Grenada in 1983; all three Ranger battalions, plus HQ elements, for the U.S. invasion of Panama (Operation Just Cause) in 1989; Bravo Company, 1st Battalion was deployed in the First Persian Gulf War (Operations Desert Storm and Desert Shield) in 1991; Bravo Company, 3rd Ranger Battalion was the base unit of "Task Force Ranger" in Operation Gothic Serpent, in Somalia in 1993, concurrent with Operation Restore Hope; soldiers from the 1st, 2nd, and 3rd Ranger Battalions deployed to Haiti in 1994 (before operation's cancellation; recalled 5 miles (8.0 km) from the Haitian coast); and the 3rd Ranger Battalion led the attack in Afghanistan, in 2001; the entire Ranger Regiment is on deployment since the start of the current Iraq War, in 2003.
Due to the changing nature of warfare and the need for an agile and sustainable Ranger Force, the Regimental Special Troops Battalion was activated 17 July 2006. The RSTB conducts sustainment, intelligence, reconnaissance and maintenance missions which were previously accomplished by small detachments assigned to the Regimental headquarters and then attached within each of the three Ranger battalions.
