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.

Company-size delay and fall back fighting and protective positions are most often prepared. General engineering missions support theater armies with both vertical and horizontal construction capabilities. The maximum spacing between e standard pickets used to support e excellent for use in revetting.

The staff input in the decision-making process for planning survivability missions includes: Always place a waterproof FM layer over any survlvability cover to prevent it from gaining moisture or weathering. Then, the Maximum Span table shows that support of the Vk feet of cover using 2 by 4 roof stringers over a 4-foot span requires inch center-to-center spacing of the 2 by 4s. Proper position siting can lessen the problem of surface water runoff.

The immediate construction phase is characterized by the coordinated effort of infantry, artillery, and engineer forces to produce a tenable tactical position by nightfall on the first day. In restricted terrain such as cities, forests, or mountains, light infantry units are also a challenge to enemy armor forces. Friendly situation and survivability support resources are evaluated.

Thermal, blast, and radiation effects require separate consideration when designing protection. Field Manual provides chemical agent details and characteristics.

FM 5-103 Survivability

During construction, adequate frontal and perimeter protection and observation are necessary. 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.

Recommended priorities for protection at a halt in the survivanility are- Antitank weapons. A continuous brush revetment is constructed in place. Weather could cause structures made of snow or ice to wear away or even collapse.


The engineer’s ultimate role in survivability is set by the maneuver commander controlling engineer resources. Inner rows are spaced equal distance from the outer rows at distances not exceeding two times the borehole depth. Supply and equipment constraints are identified through analysis of on-hand supplies, naturally- available materials, and supplies available through military and indigenous channels.

Field artillery is capable of suppressing enemy direct fire forces, attacking enemy artillery and mortars, suppressing enemy air defenses, and delivering scatterable mines to isolate and interdict enemy forces or protect friendly operations. Samples of expedient protective positions: Depending on the density of the foliage on the site, completion of the initial clearing phase by combat engineers with demolitions and chain saws may sjrvivability up to 3 hours. The few natural or locally-procurable materials which are available in jungle areas are usually limited to camouflage use Position construction materials are transported to these areas and are required to be weather survivaility rot resistant.

The primary means for aircraft protection on the ground is a combination of terrain masking, cover and concealment, effective camouflage, and dispersion. Survivaiblity rnquirDF a hijh degrra ol Bncjimer effort: Parapets are also used as a single means of protection, even in the absence of excavations. It is impossible to divide responsibilities in survivability missions between the maneuver commander and the engineer commander. The following AirLand battle conditions will shape our protection and survivability efforts: To create ramps for positions in relatively flat terrain using explosives, the lower portion is excavated as a rectangular position, as shown, and the upper end is excavated by hand.


Almost twice as many soldiers are killed or wounded by small caliber fire when their positions do not have frontal cover. The successful force must have enough flexibility to recognize and make immediate necessary changes on the battlefield. Thus, they may require substantial protective construction.

These irregularities weaken rock and can increase penetration. Incendiary and chemical effects are generalized from the previous survivabilitj of weapons effects.

The time required to complete this phase depends on the terrain at the firebase site. Survivability 5-03 enhance the total survivability of the force through fighting and protective position construction.

Protection for a minimum of 40 patients is required as soon as possible. If the bags are filled from a stockpile, the job is performed easier and faster by using a lumber or steel funnel as shown on the right.

In urban areas, existing structures offer considerable protection. Views View Edit History. This manual is intended for engineer commanders, noncommissioned officers, and staff officers who support and advise the combined arms team, as well as combat arms commanders and staff officers who establish priorities, allocate resources, and integrate combat engineer support.

As a general rule, deeper excavation is desired for other than fighting trenches to provide more protection or allow more headroom.
