What phrase is typically used to signify readiness for action in a law enforcement context?

The phrase that signifies readiness for action in a law enforcement context is often "All units proceed to _." This phrase indicates that all responding units are to move forward to a specified location or engage in a specific operation. It conveys a clear and direct order that implies everyone is ready to take the next step without hesitation.

"Are we clear to/for _?" would typically be used to check if there are any obstacles or legal issues before proceeding, rather than indicating readiness. "Stand by for further instructions" suggests that there will be a delay and that units should wait rather than act. "Proceed with caution" indicates that there might be a potential risk or uncertainty, prompting a careful approach rather than an all-out readiness for action.

Thus, the phrase that most effectively communicates an immediate readiness to act is "All units proceed to _."
