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.

Agents do not destroy material and structures, but make them unusable for periods of time because of chemical contaminant absorption. Battlefield survival critically depends on the quality of protection afforded by the positions. As countermobility activities are completed, engineers will help improve those survivability positions.

This image is a work of a U. If 4 by 4 stringers are positioned on 9-inch center-to-center spacings over a span of 8 feet, then 2 feet of soil loose, gravelly sand is required to defeat the burst.

Periodic inspections of sandbags are made. The maneuver commander establishes engineer work priorities and sets priorities for tasks within the functions just mentioned. The principal initial casualty producing effects are blast, thermal radiation burningand nuclear radiation. If shelters and bunkers are properly constructed with appropriate collective protection equipment, they can serve as protection against chemical and biological agents.

The first material required fo with the triggering the incoming shell b shells.

FM 5-103 Survivability

Vehicle protection is usually deep-cut type, with maximum advantage taken of protection offered by terrain and vegetation. Their fire degrades the effectiveness of enemy survivanility and reconnaissance aircraft by forcing the enemy to evade friendly air defense. Many of the shelters described in the next section Special Designs are adapted for aboveground use 5103 decontamination operations, clothing exchange, or bath points.


Survivability requirements for a defensive operation might receive the commander’s first priority for engineer work.

Facing revetments are preferable to wall sloping since less excavation is required. Initial effects occur in the immediate area shortly after detonation and are the most tactically significant since they cause personnel casualties and material damage within the immediate time span of any operation.

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 take up to 3 hours.

In urban areas, existing structures offer considerable protection. The deliberate shelters are generally well-suited to these activities. These chemical strikes are aimed at destroying opposing force offensive capability, as well as disrupting logistics and contaminating all vulnerable rear area targets. The best shelter is usually one that provides the most protection but requires the least amount of effort to construct. Tha zijzag tract has: Finally, covered sudvivability between these positions are selected, and camouflage of all structures is accomplished.

Deep-supported tunnels and positions provide protection from other fuel-air munitions and explosives. Special combinations and modifications are made to meet battlefield demands. Continued improvements are made to strengthen the position during the period of occupation. Air-delivered weapons such as ATGMs, laser-guided missiles, mines, and large bombs require similar survivability considerations.


Preventing water from flowing into the excavation is easier than removing it. Additionally, covert reconnaissance missions or sabotage and harassment missions are accomplished by small Threat teams deployed in the rear.

Fuel-air munitions create large area loading on a structure as compared to localized loadings caused by an gm weight high explosive FM charge.

Major FM considerations for camouflage surviivability are discussed in appendix D. Survivability Considerations Direct fire survivability considerations include oblique impact, or impact of projectiles at other than a perpendicular angle to the structure, which increases the apparent thickness of the FM structure and decreases the possibility of penetration.

Using the protection criteria discussed earlier, and an up-to-date detailed terrain analysis portraying the degree of natural protection, a commander develops and ranks a detailed tactical construction plan to support survivability efforts. Shielding against direct fire projectiles survivabiljty initially stop or deform the projectiles in order to prevent or limit penetration.


Thus, the basic protection requirements are simple positions for individuals and crew-served weapons. Critical survivability tasks in built-up areas include preparation of- ATGM positions. Tunneling in hard rock is slow and generally impractical. Each sandbag is then pounded with a flat object, such as a 2 by 4, to make the retaining wall more stable.
