REVETMENTS<br />

5.1. Overview. Revetments are generally defined as raised walls or structures<br />

designed <strong>to</strong> provide protection against bombs, rockets, grenades, small arms<br />

fire, and the effects of blast and fragmentation. Revetments can be as simple<br />

as a wall of sandbags or as elaborate as major construction projects involving<br />

permanent, hardened revetments and aircraft <strong>shelters</strong> (Figure 5.1). Revetments<br />

of sufficient height can be used <strong>to</strong> provide full sidewall protection<br />

around open s<strong>to</strong>res of critical equipment and material assets. Revetments can<br />

also function as <strong>obstacles</strong> <strong>to</strong> vehicles and other forms of possible intrusion. In<br />

the expeditionary environment, revetments are commonly composed of a soil<br />

berm and some type of structural material used as a retaining wall <strong>to</strong> hold<br />

back and stabilize the mass of earth. This type of revetment can be very effective<br />

against blast and fragmentation effects. This chapter covers the different<br />

types of revetments that can be used for a variety of purposes in the expeditionary<br />

environment.<br />
