Which agency provides intelligence support to military operations through signals intelligence?

The agency that provides intelligence support to military operations through signals intelligence is the National Security Agency/Central Security Service. This institution plays a vital role in intercepting, deciphering, and analyzing signals intelligence (SIGINT) from various sources, which includes communication and electronic data. This intelligence is crucial for military operations, as it provides decision-makers with insights into enemy movements, strategies, and capabilities.

The authority of the National Security Agency extends beyond just gathering intelligence; it includes processing and distributing this information to relevant military and government entities, thereby enhancing operational effectiveness. Their expertise in signals intelligence is a core component of the United States' intelligence community, ensuring that military operations are informed and strategic. This capability establishes them as a central player in maintaining national security through effective communication surveillance and data analysis.
