A terrorist attack has occurred or is likely against a specific location refers to which TREATCON condition?

The scenario described—where a terrorist attack has occurred or is likely against a specific location—corresponds to TREATCON Delta. This condition indicates an imminent threat level where additional protective measures and readiness are required due to heightened risk, including the confirmed presence of terrorist threats.

Under TREATCON Delta, units are expected to implement the most stringent security measures because the situation is critical enough to warrant immediate action. The focus during this condition is on ensuring the safety and security of personnel, as well as protecting facilities from potential threats.

In contrast, TREATCON Alpha involves a low level of heightened alert, where there is general awareness of a potential threat but not an imminent danger. TREATCON Bravo indicates a more elevated state of alert, where there is a specific threat against a given target, but not to the extent observed in Delta. TREATCON Charlie is utilized for situations where a terrorist attack is imminent or has occurred, but it typically refers to a broader scope or continued response beyond just one specific location.

Therefore, recognizing that TREATCON Delta represents a state requiring urgent attention justifies why this level is designated for circumstances involving direct threats against a specific target or location.
