3. Lost persons often fight topography and are likely to be found in the most rugged portion of the surrounding country. Persons who follow natural routes are seldom lost for long periods. Children under 5 years old frequently travel uphill. B. Search Patterns 1. Parallel patterns are generally the most effective for land search. Execution requires a team leader, normally two flankers, and as many linemen as the terrain will allow. The searchline is first formed along the search area boundary, with individual linemen positioned one track spacing apart. The team leader maintains overall team control in the same manner an OSC maintains control of a multiunit search. Boundary control of each successive sweep through an area is normally assigned to the pivoting flanker. a. After the searchline is formed, it moves forward on a signal from the team leader. Linemen remain evenly spaced as the team progresses. If part of a team encounters an obstacle, they should investigate it while the rest of the team continues just past the obstacle and stops to wait. When the checkers have rejoined the searchline, the entire searchline again moves forward on signal of the team leader. b. When the searchline completes its first search leg, it does not use the flanking movement of a multiaircraft or multivessel searchline to reposition itself for the second searchleg. Instead, the land SRU will use a pivoting movement about the flanker. As each sweep is made, the inboard flanker is blazing the line of search, possibly with a string. At the end of the searchleg the searchline pivots about that flanker, and then is guided by the same flanker on the return searchleg, retracing the blaze line. Meanwhile, the other flanker is blazing a search track during the second searchleg, and will be the pivot flanker for the maneuver between the second and third sweeps (see Figure 8-4). 2. Contour patterns are normally used for mountainous or steep terrain. Their execution requires a team leader, normally two flankers, and up to 25 linemen. The searchline is initially 8-7
Figure 8-4. PM Search Pattern for Land SRU formed on a line perpendicular to the ridgeline or on a radial from the mountain top. The team leader maintains overall team control, with sweep boundary control assigned to the upper flanker. a. The searchline of the contour pattern starts at the highest level to be searched. It maintains a constant altitude during each sweep, and progresses down the slope on successive sweeps. When the searchline completes each sweep, it reforms on the low side of the bottom flanker. The lineup order is reversed as in the parallel pattern pivoting maneuver between search sweeps. The line then continues the search moving in the same direction around the mountain as was followed on previous search sweeps. Searchline checking, starting, and stopping are all controlled by the team leader, as when executing a parallel pattern. b. Contour patterns are also useful for terrain that prevents using straight searchlegs efficiently, such as long irregular shorelines or other irregular terrain. This procedure may require special SRUs to cover areas missed by the weaving searchline.
