Applicable to:	BuildingTypes

This flag, when set to yes, will turn the structure into what has been called a "Threat Rating Node". This alters the AI of your units slightly, so that they assess incoming threats to a better extent than they did before. Basically, upon this being built, your objects will switch over from using the "dumb threat" coefficients defined in General and instead use the "default threat" coefficients instead.

A side effect, however, due to the Threat Rating Node's somewhat broken logic, is that the effect is permanent for the rest of that game. When the Threat Rating Node is destroyed, the effect will still remain regardless of whether it is rebuilt or not, and the player's units will still have the benefits of it.

According to an Ares developer, this flag is inactive since Tiberium Sun. The flag is globally active via house settings and the "default threat coefficients" are always in effect. Even the function that would deactivate the flag activates it instead.
