The three response categories and their deployment standards are as follows: (1) Priority (gold). Priority response (gold) requires the deployment of an advanced party of the WMD-CST no later than 90 minutes after the official time of notification (N) and deployment of the remaining WMD-CST no later than N + 3 hours to support a response anywhere within the Nation. (2) Ready (silver). Ready response (silver) requires units to focus on preparing for possible priority response missions outside their home state. WMD-CSTs in this phase, once directed, must deploy to the event no later than N + 24 hours. (3) Standby (bronze). Standby response (bronze) requires units to focus on areas such as training requirements and leave. WMD-CSTs in this category, once directed, must prepare for and deploy no later than N + 72 hours. WMD-CSTs that are not mission-capable (black) are unavailable for deployment. (DA, WMDCST Operations, December 2007, p. 2-1)
