What term indicates that a joint terminal attack controller grants weapons release clearance to an aircraft to attack a target?

The term "Cleared to Engage" is the standard phrase used by a joint terminal attack controller (JTAC) to give weapons release clearance to an aircraft for an attack on a specified target. This phrase clearly communicates to the aircrew that they have the authority to initiate the attack, ensuring coordination and safety between ground forces and aircraft.

Using such a standardized terminology is crucial in military operations to avoid confusion and ensure that all parties involved understand their roles and responsibilities during a strike. It indicates that all necessary checks have been performed, and the aircraft can proceed with the engagement based on the current rules of engagement and target identification.

The other options like "Continue," "Go for Attack," and "Ready to Fire" do not carry the same operational significance or clarity. They could potentially lead to misunderstanding among personnel about the authority to engage or the status of the target, highlighting the importance of precise language in combat scenarios.
