Unformatted text preview: t team should not make either of the projected lines (from the FRPs to the point of emplacement) more than twice as long as the baseline (between the two FRPs). If personnel maintain this proportion, the only limitation on the length of the projected lines is the length of the measuring line that the recovery party carries. The recovery party should carry two measuring lines when the emplacement team uses this method. SIGHTING THE CACHE BY COMPASS AZIMUTH D-25. If the above methods of sighting are not feasible, personnel may project one measured line by taking a compass azimuth from the FRP to the cache placement point. To avoid confusion, personnel should use 30 November 2010 TC 18-01 D-5 Appendix D an azimuth to a cardinal point of the compass (north, east, south, or west). Since compass sightings are often inaccurate, personnel should not place caches pinpointed by this method more than 10 meters from the FRP. MEASURING DISTANCES D-26. The observer should express all measured distances in a linear system that the recovery party is sure to understand—ordinarily, the standard system for the country where the cache is located. He should use whole numbers (6 meters, not 6.3 or 6.5) to keep his instructions as brief and simple as possible. To get an exact location for the cache in whole numbers, the observer should take sightings and measurements first. D-27. If the surface of the ground between the points to be measured is uneven, the observer should measure the linear distance on a direct line from point to point, rather than by following the contour of the ground. This method requires a measuring line long enough to reach the full distance from point to point and strong enough to be pulled taut without breaking. MARKING TECHNIQUES D-28. The team can simplify the emplacement operation and save critical time if the observer marks the cache point during his reconnaissance. If the team plans a night burial, personnel may need to mark the point of emplacement during a daylight reconnai...
