Which A-series function represents Intelligence, Surveillance, and Reconnaissance?

• A. A3
• B. A7
• C. A2
• D. A6

Answer: (C)

Intelligence, Surveillance, and Reconnaissance centers on turning sensor data into actionable knowledge for decision-makers. The A-series function that represents ISR is the one whose duties include planning and conducting collection, processing and analyzing information from multiple sensors, and delivering timely intelligence products to commanders. This end-to-end flow—from sensor tasking to data fusion to dissemination—defines ISR within the A-series framework, making it the best fit for the question. Other A-series functions focus on different mission areas and do not center on collecting and interpreting sensor information, so they don’t fit ISR.
