Chapter 7and concealment (OAKOC) methodology (see FM 7-92). Typical locations for enemy IED emplacementinclude―• Bridges and overpasses.• Road and rail intersections.• Places that force slowdowns and closer intervals on convoys, such as winding turns, unpavedsurfaces, steep or sharp turns, narrow roadways, and choke points.• Areas of dense civilian traffic or congestion.• Culverts or tunnels.• Terrain that provides overwatch.• Terrain that offers cover or concealment for IEDs and initiators.• Terrain used for marshalling personnel, equipment, and supplies.WEATHER7-43. Weather and the climate have direct and indirect effects on IEDs. The weather affects―• The visibility of IEDs, initiators, and targets.• The selection of emplacement for IEDs.• The effectiveness of IEDs. For example, low and dense cloud cover may increase the blasteffects of an IED. Temperature and moisture may cause failure to initiate or prematuredetonation.TROOPS AND SUPPORT AVAILABLE7-44. When given a mission, a leader does a troop-to-task analysis. This analysis of troops and supportavailable includes the number, type, capabilities, and condition of available friendly troops and support. Italso includes supplies and support available from joint, multinational, and interagency forces. Commandersconsider available troops and support when analyzing whether they have enough resources to accomplish amission.7-45. The types of units and support that commanders should consider for IED defeat operations include―• Intelligence support, to include HUMINT, SIGINT, IMINT, and CI.• Reconnaissance assets, to include reconnaissance units, scouts, and unmanned aerial vehicles(UAVs).• Engineer units and support, to include mobility augmentation companies, clearance companies,Sapper units, search teams, and specialized search dog teams.• EOD units or personnel.• Combat forces, to include maneuver and fire support units.• Linguist support.• CA support.• Military police units.• Psychological operations support.TIME AVAILABLE7-46. Leaders must take into account the ability of their unit and subordinate units to plan, prepare, andexecute operations within the time available. The ability of the enemy to plan, prepare, execute, and react isalso a function of time. Within IED defeat, many operations are time-sensitive. They include—• Convoying route change detection.• Responding to an IED incident (EOD render safe and disposal, forensics, and so forth).• Targeting.• Raiding an IED maker or factory.• Seizing stockpiled caches.7-12 FMI 3-34.119/MCIP 3-17.01 21 September 2005
