The operational search event under consideration may be a one-time (completed) event or a specific process, a system of organizational, tactical, intelligence and search activities carried out mainly by secret forces, means and methods, the choice of which is dictated by specific circumstances and tasks of the ORD. With this in mind, for example, a survey, observation, operational experiment can be considered as its auxiliary elements, components of the preparation of operational implementation or intelligence and search activities of embedded entities. Operational implementation should be considered not only as a process of entry, penetration in order to collect information, but also as an intermediate or final result in the form of: fixing on the object of implementation; gaining access to information of interest to the operative as a subject of the ORD; creating circumstances conducive to obtaining information by embedded persons; conducting search and reconnaissance activities by them; identifying persons and facts of operational interest; establishing contact (trust relations) with identified persons; collecting operational information, carrying out other activities in order to solve the tasks of the ORD.
