contact with the enemy, thereby forfeiting their ability to remain concealed and avoid detection and/or engagement. The only units within the United States Army to specialize in the capability and skill of the LRS mission are those of the LRS units within the BfSBs, Special Forces (SF) Operational Detachments-Alpha (SFODAs, ODAs, or A-Teams), and the Ranger Regimental Reconnaissance Company (RRC) of the 75th Ranger Regiment. The BfSB’s R&S squadron is composed of one LRS unit (i.e., Company C), which contains 15 LRS teams. Additionally, the R&S squadron also has two Cavalry troops (each containing two platoons) that conduct basic mounted and dismounted operations, and a headquarters and headquarters troop (HHT). For a standard six-soldier LRS team, the primary method of insertion/infiltration behind enemy lines is at night by helicopter (night-time heliborne), while secondary methods include airborne and waterborne operations. In recent low-intensity conflicts, additional covert methods have been added to enable enhanced operational capabilities. Airborne reconnaissance missions are conducted by the three aforementioned types of United States Army units: LRS units, SF ODAs, and the Ranger RRC. Contrast with Reconnaissance, Surveillance, and Target Acquisition (RSTA) Units Although both are types of units in the United States Army, LRS units (Airborne Infantry) are not to be confused with the newer concept of RSTA units (non-Airborne Cavalry). As part of the Army-wide transfer to brigade combat teams (BCTs), all combat divisions and separate brigades are transitioning to RSTA units. RSTA units also have added light vehicle support in the form of Humvees (HMMWVs) and M3 Bradley Cavalry Fighting Vehicles (CFVs), due to being commissioned as Cavalry. LRS units, in contrast, do not utilize a larger vehicle support element. As previously stated, RSTA units are not Airborne-capable, whereas most LRS units are. However, exceptions are the RSTA squadrons of the 2nd BCT (Airborne), 11th Airborne Division; the 173rd Airborne BCT; and the four RSTA units in the 82nd Airborne Division). By doctrine, RSTA units do not require their leadership positions to be filled by Ranger-qualified commissioned and noncommissioned officers, whereas LRS units desire additional skills and special qualifications. Equipment LRS Soldiers typically carry weapons that include the following: M4 carbine, M9 pistol, M249 Squad Automatic Weapon (SAW/LMG), M203 grenade launcher, as well as mission-specific gear, including (but not limited to), optics, A/V recording devices, secure communications gear, etc. Training Since LRSUs are Airborne operations capable, the Soldiers serving in these units must be
