No, personal phones are generally not allowed for use by students during Ranger School, with limited exceptions for official or emergency communication.
While personal cell phone use is restricted, communication with the outside world is not entirely cut off. The Airborne and Ranger Training Brigade typically provides access to pay telephones at most training locations for students to use during designated times. These phones are intended for emergency use or for making brief calls home. However, pay phones are not available at Camp Darby, Fort Benning, Georgia.
It is important to note that this policy is designed to maintain focus on training and to prevent unauthorized communication that could compromise the integrity of the course. Communication policies can evolve; therefore, the most up-to-date and accurate information can be obtained from the official Ranger School documentation or directly from the Airborne and Ranger Training Brigade.
