26 October 2021 ATP 3-09.12 E-1 Appendix E Support Requirements WLRs are widely dispersed across the AO and require support from units that may not be familiar with the support requirements for the WLR. Appendix E outlines the support requirements. SURVEY E-1. Common datum and common survey is critical for successful employment of WLR systems. The specific survey data required for each WLR system is described below: Survey data Grid zone. Site location (universal transverse mercator coordinates within 10 meters circular error probable). Distance from near stake (WLR location) to far stake (orienting point). This distance between near and far stakes should be at least 250 meters. The minimum distance is 100 meters. However, the further the distance the better the accuracy that the system will report. Azimuth from near stake to far stake (0.4 mils probable error). Vertical angle from near stake to far stake (0.5 mils probable error). Altitude of the near stake (10m probable error). E-2. The AN/TPQ-36 radar is equipped with the modular azimuth positioning system-hybrid (MAPS-H). The MAPS-H provides required survey for the radar systems. MAPS-H will be initialized using input from a common survey point or the Defense Advanced Global Positioning System Receiver (referred to as the DAGR). Once initialized, the MAPS-H will be continually updated by input from the DAGR, if installed. For initialization, operation, and update information refer to TM 11-6605-308-12&P. SUSTAINMENT SUPPORT E-3. When the WLR section is attached to a unit, the unit of attachment is responsible for providing routine personnel, administrative, and sustainment support. The WLR section's parent unit forwards mail, pay, and routine distribution to the unit of attachment's HQ for delivery to the WLR personnel. FIELD MAINTENANCE E-4. Field maintenance is on-system maintenance, repair and return to the user, including maintenance actions performed by operators. It is most often performed by the owning or support unit using tools and test equipment found in the unit. Field maintenance is not limited to simply remove and replace actions. Field maintenance allows for repair of components or end items on or near the system if the maintainers possess the requisite skills, proper tools, proper repair parts, references, and adequate time. E-5. Within the FAB, field maintenance for items other than WLR systems is performed by the assigned forward support company. TAP and maintenance personnel of the assigned corps support BN share WLR field maintenance responsibilities. The radar section chief supervises operator maintenance within the TAP. WLR section and forward support company personnel perform operator and field maintenance at the BCT FA BN level.
