Buried and concealed mines gure By using full-width mines, the probability of kill increases for the minefield. Improvised, electric delay devices AHDs and low-metallic mines are operatiins used so that the minefield can be easily recovered. The pressure plate has an indented, yellow arrow that points to the A or S position on top of the fuse body. A fully matured lane is one that will support uninterrupted, twoway traffic. The farside final-approach marker is centered on the lane and placed meters mounted forces or 30 meters dismounted forces from the exit.

Full lane marking each way.

Metal collar on an M fuse A gureA This protects units from inadvertently traveling an uncleared route. An AHD does not have to be attached to the mine; it can be placed underneath the mine Figure Guide markers are not required for an air Volcano minefield because the pilot will use the start and end points of the centerline as reference points.

Skip zone gure The decision to mark individual minefields or obstacle groups should not be based solely on logistical considerations. Units must clear LOC of obstacles and enemy activity that disrupt battlefield circulation.

The decentralized emplacement of protective obstacles makes consolidating reports and records difficult and requires command involvement. A supply request includes the quantity, the required delivery time, the transportation responsibilities, and the desired delivery location. A minefield is an area of ground that contains mines or an area of ground that is perceived to contain mines a phony minefield.


The emplacing unit OIC signs the signature block.

If the mines have not self-destructed, the minefield is marked before the unit leaves the area or turns it over to an adjacent unit. Figure also provides general guidance for varying the mine density to yield the necessary probability of encounter when developing disrupt, fix, turn, and block minefields. Hornets are emplaced beginning on the friendly side of the cluster. They also mark mines for destruction by explosives.

Activated by several methods— acoustics, magnetic- influence, tilt-rod, radio-frequency, infrared-sensored, command, or vibration. Protective minefields are used in both close and rear operations, and they are operation as either hasty or deliberate: Normal parameters for threat-style minefields C-2 Table D-l.

An obstacle is an excellent location for preplanned artillery and mortar fires.

Booster charge may be attached to the fuse or the igniter or be part of the main charge. When using a ground-delivery system, minefield marking must leave a gap along each centerline for vehicle entrance and exit.

M15 mine in the hole A gureA Mines nearest the enemy are armed first, allowing soldiers to safely work their way back to the unit position. minne

Preliminary hazard-analysis work sheet disarming M19 E Figure E As the engineer platoon moves to the mine dump to resupply, each emplacing vehicle loads a designated mine-strip package. Obstacle siting concentrates on marking the obstacle group as a whole instead of marking each individual obstacle.

Tactical versus protective obstacles gure Mines with AHDs are sometimes incorrectly called booby-trapped mines. I n short, this numeric value helps determine the amount of linear obstacle effort that is needed to achieve the desired effect. Although the blast wave is accentuated by underwater placement attacking hatches and coversmining of banks and approaches is recommended instead. This gives a total minefield depth of meters ground or meters air.

Individual block obstacles are employed successively in a relatively shallow area. Depending on the size and the location of minefields, either technique may have the advantage of using fewer resources or labor. The emplacing engineer must always be cognizant of the sustainment traffic flow and the impact obstacle emplacement has on sustainment operations. The preponderance of mine composition is designed against the most severe close-combat threat and the likelihood of that threat.

The engineer provides critical information using the scheme-of-obstacle overlay and the obstacle-execution matrix. After the S2 and the engineer identify the most probable threat sites, the S2 designates them as NAIs.

A fix effect may be used to generate the time necessary for the force to break contact and disengage as the enemy maneuvers into the area typically used for delays. If a scatterable minefield is selected, he recommends the delivery system and coordinates the minefield with appropriate staff officers.

Coumtermine of clusters in a mine strip AP mines are left in their crates, and the crate lids are counterminee. The injuries and deaths they cause commit medical resources, degrade unit morale, and damage nonarmored vehicles.
