This image is a work of a U.S. military or Department of Defense employee, taken or made as part of that person’s official duties. As a work of the U.S. federal. This page contains the US Army Field Manual on Survivability. FM Survivability on the modern battlefield, then, depends on progressive development of fighting and protective positions. That is, the field survivability.

United States Forces United States defending forces conduct extensive survivability operations during an enemy attack. Operating personnel need both individual fighting positions and protective positions. However, burlap and chicken strength or durability of plywood or ng soil.

It is also effective against thermal radiation, although it transmits heat rapidly. When available, natural shelters such as caves, mines, or tunnels are used instead of constructing shelters. Overhead cover is necessary because soldiers are at least ten times more protected from indirect fire if they are in a hole with overhead cover. As time permits, shelters are continuously improved. Armor units enhance protection by constructing alternate and supplementary positions and defining routes between them.

Hasty positions are continuously improved into deliberate positions to provide maximum protection from enemy fire. If the site is covered with foliage and trees, the security force and combat FM engineers are required to descend into the site from hovering helicopters.

These are usually small tunnels with entrances normally closed or concealed. When sudvivability position diameter fmm not exceed twice the borehole depth, a single charge placed at the center of the position is enough.

The maneuver commander must rely on the engineer staff officer or supporting engineer commander to provide analyses and recommendations for protective construction and fighting position employment. With the assistance of combat engineers, the infantry troops also begin placing the first band of tactical wire, usually triple standard concertina.


The space behind the pickets is packed with small, straight brushwood laid horizontally. Protection from these effects creates a large demand for engineer equipment, materials, and personnel.

Supply shelters are of any size, depending on location, time, and materials available. For example, the complete fighting position for a tank requires the construction of a hull defilade, turret defilade, concealed access ramp or route, and hide location all within the same fighting position. Sandbags are also useful for retaining wall revetments fj shown on the right. Several concentric rings of holes are needed for large positions, and one ring or only one charge for small positions.


Following is a discussion of materials used to build floors, walls, and roofs of positions.

The meeting engagement begins as the Threat advance guard of a combined arms force makes contact with the enemy advancing force.

Parapets positioned at the front of or around major weapons systems will provide improved protection from direct fire and from blast and fragments of indirect fire artillery, mortar, and rocket shells. In addition, the commander uses the division intelligence system which provides the Threat order of battle and war-damaged key facilities. Covered routes between buildings. Parapets around positions are kept clear and wide enough to prevent parapet soil from falling into the excavation.

The charge layout shown on the right is as follows: However the plaLfijiivi is cky to keup- the g ur Ira nsvef bb ble acre ss the enllro- ttttot uf fire.

In the next fast-paced battle, our survivabilitty must protect themselves as never before from a wide range of highly technical weapons systems.

The speed of excavation using hand tools varied according to the soil, and seldom exceeded 25 feet per day. A strong-point is not setup on a routine basis. Fuel-air munitions create large area loading on a structure as compared to localized loadings caused by an equal weight high explosive FM charge. Fill tldif Survivagility Vjillf. However, if natural frontal protection is not adequate for proper protection, dirt excavated from the position hole is used.

Forward Support Maintenance In a highly fluid battle situation where frequent displacement of the forward support company is survivabiliy, the company cannot afford the effort required to construct extensive protective positions and shelters due to conflicts with basic mission accomplishment. Army 5-03 Manual Field Artillery Field artillery is the main fire support element in battlefield fire and maneuver. Ir ihla niirliier, u ultzllnw Kjdy- krigth pit is. Therefore, priorities of construction are necessary.

In cold regions, air warmer than outside air may rise from a tunnel entrance thus revealing the position. For example, the DS terrain team, the production survigability of the division tactical operations center DTOC support element, and the corps cartographic company can quickly provide required terrain products. As a work of the U.


FM 5-103 Survivability

The holes are spaced no farther apart than twice their depth, and no closer to the desired perimeter than the depth of the borehole. Parapets are generally positioned as shown below to sudvivability full frontal protection, thus relying on mutual support of other firing positions.

Thicknesses required for parapets vary according to the material’s ability to deny round penetration. This characteristic is due to the survivabioity compressive strength and hardness properties of brick and masonry.

Maneuver units have primary responsibility to -5103, position, and begin building their own positions. Once beyond the 5–103 this survivaiblity are unlimbered if they will stand open. Activities in the defense include constructing protective positions for command and control artillery, air defense, and critical equipment and supplies.

Design and construction of shelters with adequate overhead cover is mandatory so medical care and treatment are not interrupted by hostile action. The materials used in fighting and protective position construction act as either shielding for the protected equipment and personnel, structural components to hold the shielding in place, or both. A structure high, or where there is a fighting position platform provides a floating base o resistance soil precludes constructed of small branc posts, thus distributing t shown in the following ill are quickly constructed us as ponchos or survivabjlity mate detailed information on ju igh water tables, dense undergrowth, iring above-ground level protective used in areas where groundwater is low- pressure resistance soil, is thedepicted below.

The individual soldier carries an entrenching tool and has access to picks, shovels, machetes, and hand carpentry tools for use in individual excavation and vertical construction work.

Increased engineer requirements on the AirLand battlefield will limit engineer resources supporting survivability. Its firepower, protection from enemy fire, and speed create the shock effect necessary to disrupt the enemy’s operations. Threat situation and Threat direct and indirect assets are analyzed.
