denis-greek [22]

Answer:

Intelligence

Explanation:

Intelligence is the product resulting from the collection, collation, evaluation, analysis, integration, and interpretation of collected information. It is a specialised information product that provides an adversary with information required to further its national interests. One of the most important functions of intelligence is the reduction of the ambiguity inherent in the observation of external activities.rations.  

In most cases, the development of an intelligence product involves collecting information from a number of different sources. In some cases, information may be disseminated immediately upon collection based upon operational necessity and potential impact on current operations.

Strategic intelligence provides policy makers with the information needed to make national policy or decisions of long-lasting importance. Strategic intelligence collection often requires integrating information concerning politics, military affairs, economics, societal interactions, and technological developments. It typically evolves over a long period of time and results in the development of intelligence studies and estimates.

Operational intelligence is concerned with current or near-term events. It is used to determine the current and projected capability of a program or operation on an ongoing basis and does not result in long-term projections. Most intelligence activities support the development of operational intelligence.
