26 October 2021 ATP 3-09.12 G-1 Appendix G Rocket Artillery and Mortar Warn This appendix describes rocket artillery mortar (RAM) warning (Warn) techniques. RAM Warn provides the commander and the supported unit with an early warning capability of imminent rocket artillery or mortar attack to enable the affected personnel the ability to protect themselves from the effects of the attack. OVERVIEW G-1. RAM Warn provides Soldiers, staff personnel, and operators with automated warnings and enhanced alerting capabilities. RAM Warn integrates the BCT organic sensors, commercial off-the-shelf warning systems and communication devices, and the forward area air defense (FAAD) workstation in the ADAM element. The RAM Warn capability is integrated into the ADAM element architectures to provide warning to forces and assets as determined by the commander. Without detection capabilities and C2, RAM Warn is inoperable. RAM Warn integrates and operates with Army Battle Command System for battlefield situational understanding. The RAM Warn system is generally designed to be used in fixed and semi fixed sites, however there may be situations in a fluid, maneuver, decisive action event where the RAM Warn system may be employed. G-2. RAM Warn is a dynamic, modular, and readily-transportable system that provides incoming RAM attack warnings. RAM Warn supports the BCT's force protection mission by performing the following: Issuing guidance and orders. Delivering audible and visual alerts. Maintaining situational understanding. Supporting dynamic, joint-forces integration operations. G-3. RAM Warn sensor links consist of line-of-sight radio transmitters at sensor locations connected through a retransmission site, if necessary, to the ADAM element operating a FAAD computer with counter rocket artillery and mortar Warn services software. RAM Warn communication devices can cover up to 15km distance between the sensors and the ADAM element; or 30km with the use of relay equipment. The transmitter and associated equipment is assigned to each sensor and a retrans section, and each section is responsible for the employment and maintenance of their equipment. Figure G-1 on page G-2 shows RAM Warn architecture. G-4. Each section that has the RAM Warn system will have a mesh network consisting of radios that serves as the backbone of the Warn system. RAM Warn architecture offers two primary capabilities readily to adapt to components that are modularized, standardized, and reconfigurable. The two capabilities provide the following functions: Links the RAM Warn Alert Cell Nodes, the FAAD, and sensors (radars) through a uniquely modular, dynamic system. Computes the incoming POI information and selects the appropriate alert cell node towers within the impact zone to notify.
