Which one of the following intelligence principles is the process of collecting and examining information from all available sources to derive a complete assessment?

The principle of intelligence that pertains to the process of collecting and examining information from all available sources to derive a complete assessment is known as fusion. Fusion involves integrating data from various sources—whether it be human intelligence, signals intelligence, imagery, or open-source information—into a cohesive understanding. This process is essential in the intelligence cycle, as it enables analysts to create a comprehensive picture of a situation or threat.

Fusion enhances situational awareness by combining disparate pieces of information and analyzing them collectively, which leads to more informed decision-making. This is crucial in military planning and operations, as it ensures that commanders are equipped with the most accurate and holistic view of the operational environment.

While analysis refers specifically to the examination and interpretation of collected information to produce actionable intelligence, it does not encompass the full scope of gathering from various sources that fusion signifies. Assessment, on the other hand, typically pertains more to evaluating the effectiveness or implications of the intelligence produced, rather than the collection and integration of sources. Alignment does not directly relate to the intelligence principles in the same context as fusion does.
