Appendix A A-12 ATP 3-09.42 1 March 2016 Get the best possible grid to the center of the lane – use survey if possible; intersection or resection, if necessary. If possible, depending on mission variables of METT-TC, adjust the mission in advance onto the center point of the lane and record the adjusted location as a target. A-49. Planning for using field artillery-delivered mines to close breached obstacles should involve the S-2, S-3, engineer coordinator, FSCOORD, fires cell planners, and targeting officers. This group should identify the most likely points at which the enemy will try to breach the obstacle and how wide the breach will probably be. As with using mines to close a lane, these points should be identified by the most accurate grid attainable, fired in, and recorded as targets. Even if the enemy does not breach at these exact locations, the targets should provide accurate points from which to shift in firing mines. A-50. The FSCOORD, fires cell planners, and targeting officers must identify which observer is to fire remote antiarmor munition systems or area denial antipersonnel mines to close a breach and under what conditions the obstacle is considered breached. They should also identify an alternate observer to fire the minefield in case smoke screens, communications problems, or enemy fire prevents the primary observer from reseeding the obstacle at the proper time. This will probably require a voice call-for-fire over a command network. For more on minefields and employing minefields as obstacles or to augment obstacles see FM 3-34, FM 3-34.210, ATP 3-90.8, and ATTP 3-90.4. Employment Against Targets of Opportunity A-51. Minefields against targets of opportunity (unplanned) must be emplaced immediately because of the fleeting nature of the targets. Minefields may be requested through fire support channels at any level. Once the BCT commander has approved the use of field artillery-delivered scatterable mines, the minefields can be emplaced according to the commander’s guidance. A-52. Normally, these minefields are used against targets that can be observed or that are specifically identified by target acquisition sources, such as radar, sensors, and other acquisition devices. Their processing is similar to that of field artillery target-of-opportunity missions. Fire for effect or observer adjustment is used against either moving or stationary targets. Key considerations for employment of scatterable mines against targets of opportunity include the required density and duration of the minefield, target location, and the fire mission request. Density and Duration of the Minefield A-53. Unplanned minefields are standard in density and duration. The given standards depend on the tactical situation and the commander’s guidance. Target Location A-54. There are differing aimpoint locations for stationary targets and moving targets: Stationary target. Place the aimpoint directly over the target center. Locate aimpoints at least to an accuracy of 100 meters (adjust fire) and 10 meters (fire for effect). Moving target. Place the aimpoint for a moving target directly in front of the enemy axis of advance – 1,000 meters in front of the enemy target for every 10 kilometers per hour of speed. This allows enough time for mine delivery and arming before enemy encounter. Minefield Fire Mission Request A-55. Transmit and process the minefield fire mission request as other requests for target-of-opportunity fire missions. The standard ammunition for adjustment is dual-purpose improved conventional munitions unless the observer requests a different round. Fire the unit’s standard minefield in effect unless otherwise directed. The requestor must specify the following: Identification (call sign). Warning order (include remote antiarmor munition systems, area denial antipersonnel mines, or both). Target location (aimpoint).
