The BfSB's R&S Squadron and specifically it's LRS unit (Elite (Airborne Infantry "Recon" Company) are not to be confused with the new Army concept of Reconnaissance, Surveillance, and Target Acquisition (RSTA) units (a non-Airborne capable Cavalry basic tactical Reconnaissance unit).
By doctrine, RSTA units do not require their leadership positions to be filled by Ranger qualified officers and NCOs as LRSU units do in addition to many more specialized skill qualifications through extensive training.
