packed or cached. Teams require detailed intelligence preparation of the battlefield (IPB) and debriefing from the Intelligence Officer (G2) for employment. Organization LRS units (LRSU) are infantry company-size elements that are assets within a battlefield surveillance brigade's Reconnaissance & Surveillance Squadron (R&S Squadron) designated as US Army Cavalry but are functionally Airborne infantry units. The LRSU is structured as an LRS Company comprising three LRS detachments, a communications Platoon, and a Troop Headquarters. Within the LRS company, the LRS detachments typically have designated specialties. Typically, there are three teams, also known as "DETs." 1st DET typically specializes in mountainous terrain/warfare. 2nd DET is HALO (High Altitude, Low Open), specializing in airborne operations. This means jumping from a high-performance military aircraft at an altitude in excess of ten thousand feet and deploying parachutes at one to two thousand feet. 2nd DET can also perform HAHO (High Altitude, High Open) operations. This means jumping from a high-performance military aircraft in excess of ten thousand feet and deploying parachutes shortly after leaving the aircraft. 3rd DET is the dive detachment, specializing in water-borne operations such as scuba diving and infiltrating harbors and ports as well as employing the Zodiac. LRS detachments are organized as five unsupported LRS teams. LRS Team composition As with LRRP units of the past each US Army LRS team is composed of six soldiers: Team Leader (TL) Staff Sergeant (E-6) Preferably Ranger qualified Assistant Team Leader (ATL) Sergeant (E-5) Preferably Ranger qualified Senior Scout Observer (SSO) Specialist/Corporal (E-4) Scout Observer (SO) Specialist/Corporal (E-4) Radio Telephone Operator (RTO) Specialist (E-4) Assistant Radio Telephone Operator (ARTO) Specialist (E-4) All positions can be held by (E-1 up) to fill positions (upon meeting unit requirements) Reconnaissance and surveillance squadrons (R&S squadrons) United States Army long-range surveillance units are being reorganized into the recently introduced battlefield surveillance brigades (BfSBs). These brigades contain a brigade headquarters and headquarters company (HHC), two Military Intelligence (MI) battalions, and a reconnaissance and surveillance (R&S) squadron. The R&S squadrons conduct the same missions as RSTA units, but the R&S capabilities are vastly broader and encompass all aspects of ISR. Additionally, LRS units have the added capability of conducting strategic-level long-range surveillance (LRS) missions deep behind enemy lines. Due to this specialized capability, the R&S capability of LRS units is significantly more comprehensive than that of RSTA units. The missions of RSTA units may require them to make and maintain
