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.

The walls range from simple ones, constructed with hand tools, to more difficult walls requiring specialized engineering and equipment capabilities. Counterfire from enemy artillery is the most frequent threat to artillery units.

For protection from xurvivability fire, a hasty fighting position is located in a depression or hole at least 1 Vi feet deep. Boreholes are spaced equal distance along each ring.

Improvements include adding overhead cover, digging trenches to adjacent positions, and maintaining camouflage.

Air-delivered weapons such as ATGMs, laser-guided missiles, mines, and large bombs require similar survivability considerations. Combat engineers placing the tactical wire or clearing fields mf fire begin construction of the infantry TOG and artillery FDC.

Inner rows are spaced equal distance from the outer rows at distances not exceeding two times the borehole depth. When possible, the main Threat force maneuvers its advance guard to a flank and attacks. Ideally, this protection is provided by natural cover.

Facing Revetments Facing revetments serve mainly to protect revetted surfaces from the effects of weather and occupation. These massive artillery barrages enable the use of Threat nuclear weapons systems against targets which conventional weapons cannot destroy or disable. The following AirLand battle conditions will shape our protection and survivability efforts: Some trenches may also require widening to accommodate more traffic, survivanility stretchers.

However, fortifications effective against modern conventional weapons will vary in effectiveness against nuclear weapons. Air cavalry units, performing the same reconnaissance and security missions as ground armored cavalry, require somewhat survivbility protective construction.

Infantry and artillery troops are committed to placing the second band of tactical wire to building personnel sleeping protective positions with overhead cover.

The speed of excavation using hand tools varied according to the soil, and seldom exceeded 25 feet per day.

Always place a waterproof FM layer over any soil cover to prevent it from gaining moisture or weathering. Additional details on wall design are given in FM United States Forces United States defending forces conduct extensive survivability operations during an enemy attack. Priorities are quickly established for position development-first to antitank and crew-served weapon positions, survivabiliry then to command and control facilities and vital logistics positions.

The HEAT rounds generally range in size from surrvivability to mm. When the position diameter does not exceed twice the borehole depth, a single charge placed at the center of the position is enough. Threat doctrine emphasizes three basic forms of maneuver when attacking a defending force: This jet perforates large thicknesses of high-density material, continues along its path, and sets fuel and ammunition on fire.

The table below shows example standard survivability levels for maneuver units in defensive positions. ThiH- pnKrtirn in excelled! Survivability Considerations Survivability of chemical effects includes overhead cover of any design that delays penetration of chemical vapors and biological aerosols, thereby providing additional masking time and protection against direct liquid contamination. The rock size is approximately twice the caliber of the expected shell.

Methods of construction include sandbagging, explosive excavation, and excavation revetments. Threat acquisition and targeting activities are heavily used against artillery and are supplemented by some covert Threat deep ground attacks.

Pieces of FM brushwood about 1 survvability in diameter are weaved on a framework of sharpened pickets driven into the ground at inch intervals.

Engineer units, assisted by infantry personnel, performed the work. Survivbaility in the defense include constructing protective positions for command and control artillery, air defense, and critical equipment and supplies.

They are usually open excavations, but sections are sometimes covered to provide additional protection. When time is available and when the mission permits, revetments and parapets can protect construction equipment.

Mechanized Infantry Mechanized infantry operations in both the offense and the defense are characterized by rapid location changes and changes from fighting mounted to fighting dismounted. Equipment, such as power sources generatorsneeds protection from indirect fire fragmentation and direct fire. The backhoes are committed to excavate protective positions for the infantry TOC, artillery FDC, and, as soon as the perimeter trace is established, perimeter fighting positions.

Also, a low structure silhouette design makes a structure harder to engage with direct fire.


Trenches, as other fighting positions, are developed progressively. Field Artillery Field artillery is the main fire support element in battlefield fire and maneuver. The engineer keeps the maneuver commander informed on the level of fighting that the existing fighting and protective positions support, and what protection the covered routes provide when movement between positions occurs. Shielding against direct fire projectiles should initially stop or deform the projectiles in order to prevent or limit penetration.

Anchor wires are tightened by further twisting. Engineer support will concentrate on missions requiring unique engineer skills or equipment.
