Search Pattern Nomenclature (Ref (a), pg 5-35).
Commence Search Point (CSP). Commence Search Point is the location in the search pattern
where the SRU begins searching.
Search Leg. Search leg-is the long leg along the track of any pattern.
Crossleg. Crossleg-is the connection between two search legs.
Creep. Creep is the general direction in which an SRU moves through a rectangular or square area,
normally the same direction as the crosslegs.
Search Pattern Designation (Ref (a), pg. 5-35 & Ref (b), pg 2-F-1-30). A coded system is used to
designate search patterns. The major pattern characteristic is designated by the first letter. The second
letter denotes either a single (S) or multiple (M) unit search. The third letter designates specialized SRU
instructions. Examples: TMR-trackline multiple unit return search, VS=sector search single unit.
Trackline Patterns (T). Trackline search patterns are used when the intended route of the search
object is known. A route search is usually the first search action since it is assumed the target is near track,
and either it will be easily seen or the survivors will signal. See figure 8-4 for Trackline Single Unit Return
(TRS) search pattern.
