ECO stands for which role?

• A. Engagement Control Officer
• B. Engagement Coordination Officer
• C. Electronic Communications Officer
• D. Engagement Compliance Officer

Answer: (A)

This item tests what the ECO role actually handles in the engagement process. The ECO is the person who exercises control over engagement decisions and their execution. That means monitoring the tactical picture, validating targets, applying rules of engagement, and issuing or modifying engagement orders based on current data and command direction. The emphasis is on controlling whether and how a weapon engagement proceeds, not merely coordinating tasks or managing communications.

Engagement Coordination Officer would imply coordinating various actions across teams, but not the authority to authorize or abort a firing solution. Electronic Communications Officer focuses on the communications side, not the decision-making to fire. Engagement Compliance Officer would emphasize checking adherence to rules, but the specific authority to control the engagement itself is captured by Engagement Control Officer. So the role described by ECO in this context is Engagement Control Officer.
