FM 3-22.1d. Stinger Vision Module. The ISU has the SVM, which shows the gunner theStinger symbology, target data, and turret or launcher position, all of which he mustknow to fire the missile. Upon missile uncage, the SVM indicates the position of theStinger missile seeker. This feature is available to the gunner for all primary sightingmodes such as FLIR and DVO. The SVM with Stinger missile-tone audio improves aerialtargeting and helps the gunner to ensure that the Stinger missile locks onto the correcttarget rather than onto friendly aerial platforms or clutter. This also conserves missilesand reduces fratricide. The Stinger vision module electronics (SVME) links the SVM tothe Bradley crew evaluator (BCE). The SVME is located behind the gunner, above theEPLRS radio. The SVM, SVME, and ISU permit day and night operation of the Stingersystem and continuously send status reports to the gunner.e. Identify Friend or Foe. The IFF system provides aerial target identification.Components include the IFF antenna mounted on the right front of the turret, the IFFinterconnect box, and the IFF interrogator mounted to the right of the commander. TheIFF antenna transmits signals from the IFF interrogator and receives the response signalsfrom the aerial targets. To interrogate aerial targets, the gunner presses forward on eitherside-thumb switch on his handstation. The IFF announces the results of the interrogationover the intercom system as a series of tones.f. Stinger Control Box. The SCB is the primary operator interface for the Stingersystem. This box houses the controls and indicators for performing aerial engagementswith the Stinger missiles. It lets the gunner move the SVML electrically into any of thefollowing. (Indicator lights supply GO/Fault BIT results and firing indicators andconditions of the Stinger system):• Deployed or stowed positions• Automatic or manual stinger missile tracking• Indicator lights and lamp test• Mode switch selection of system operation.g. Gunner’s Controls. In the STINGER ENGAGE mode, the gunner’s controls caninterrogate aerial targets friend or foe; and they can activate, uncage, and fire the Stingermissile. When the gunner's controls are in this mode, the commander’s controls areinoperative.h. Interface Electronics Assembly. This assembly receives mode signals from theBCE and SCB, plus operational commands from the gunner’s control handstation, whichdirects the activating, uncaging, and firing of the Stinger missile. The IEA also processesaerial target data from the activated missile, giving the gunner a visual identificationwhen the seeker locks onto the target.i. Handheld Terminal Unit. This is a small computer terminal used to receive,process, and display aerial-targeting information, messages, and data. It is located in frontof the commander and mounts on the 7.62-mm gun door. The HTU interfaces with theFAAD PLGR for carrier position and receives aerial target information from the Sentinelradar via EPLRS radios.j. Enhanced Position-Location Reporting System. The EPLRS radio providesdigital communication between all EPLRS-equipped divisional Linebacker elements.They use the EPLRS radios to broadcast battle management and air-tracking data tothe HTU.1-6
