Manual carries must be performed correctly in order to prevent further injury to the casualty and to prevent injury to the rescuer. One-man and two-man manual carries are used to move a casualty when the time or materials needed to make a litter are not available and/or other personnel are not available to assist you in moving the casualty. In general, a casualty should not be moved before the required emergency care is given unless it is necessary to move him and yourself from a dangerous situation (enemy fire, burning building, etc.).
