5-19. Executing collection focuses on specific requirements. This collection is accomplished through the execution of tactical missions (such as the primary means of information collection: reconnaissance, surveillance, security operations, and intelligence operations) based on CCIRs and other requirements. Collection activities acquire data and information about threats and relevant aspects of the AO. They provide that information to intelligence PED and analysis elements. Typically, collection activities begin soon after receipt of the mission and continue throughout preparation and execution of operations. They do not cease after the operation concludes but continue as required. This allows the commander to focus combat power, execute current operations, and prepare for future operations simultaneously.
