b. Reconnaissance. An operation undertaken to obtain, by visual observation or other detection
methods, information about the activities and resources of an enemy or potential enemy; or to secure data
concerning the meteorological, hydrographic, or geographic characteristics of a particular area.
Reconnaissance operations are often classified according to the purpose for which they are undertaken

information (e.g., radar or ESM reconnaissance). Reconnaissance missions may be conducted by satellite,
aircraft, submarines, or surface units. It is a more limited operation than surveillance.
