Unformatted text preview: 8-01 30 November 2010 Special Forces Caching Emplacers must also consider the high-water mark to ensure that the increase in depth will not crush the container or prevent recovery. Type of Bottom D-101. Emplacers should probe as thoroughly as possible the bed of the lake or river near the cache. If the bottom is soft and silty, the cache may sink into the muck, become covered with sediment, or drift out of place. If the bottom is rocky or covered with debris, the moorings may become snagged. Any of these conditions may make recovery very difficult. Water Motion D-102. Emplacers should consider tides, currents, and waves because any water motion will put additional strain on the moorings of the cache. Moorings must be strong enough to withstand the greatest possible strain. If the water motion tends to rock the cache, emplacers must take special care to prevent the moorings from rubbing and fraying. Clearness of the Water D-103. When deciding how deep to submerge the cache, emplacers must first determine how far the cache can be seen through the water. If the water is clear, emplacer may need to camouflage the container by painting it to match the bottom. (Emplacers should always paint shiny metallic fixtures a dull color.) Very murky water makes recovery more difficult. Water Temperature D-104. Planners must consider seasonal changes in the temperature of the water. Recovery may be impossible in the winter if the water freezes. Planners should determine as accurately as possible, the dates when the lake or river usually freezes and thaws. Saltwater D-105. Since seawater is much more corrosive than fresh water, personnel should not use tidal estuaries and lagoons for caching unless they are conducting a maritime resupply operation. Maritime resupply operations involve temporarily submerging equipment along the seacoast until a shore party can recover it. CONCEALMENT D-106. There are many ways to conceal a cache in natural or ready-made hiding places. For instance, if a caching...
