What is indicated when the term "tight" is used?

The term "tight" in a fire control context indicates that systems are operational, having established secure communication and command protocols, where the Tactical Action Officer (TAO) is in control and munition is available and ready for engagement. This means that not only are the systems functioning correctly, but they are also prepared for immediate action if necessary.

Understanding the context is critical here. The reference to munition being available means that the systems are more than just operational—they are also effectively prepared for combat situations, which is what "tight" conveys in a tactical environment. This readiness status implies an assurance of both operational capability and availability of the necessary tools to engage threats as required.
