Which element of decisive action is not conducted OCONUS?

The element of decisive action that is not conducted outside the continental United States (OCONUS) is Defense Support of Civil Authorities (DSCA). DSCA primarily involves military support to civil authorities in response to domestic emergencies and disasters. It is focused on providing assistance within the United States, such as during natural disasters or significant public safety challenges where civilian capabilities may be overwhelmed.

The other components of decisive action—Offense, Defense, and Stability operations—typically involve military operations that may occur both within and outside of the United States, especially in contexts that involve international engagements, conflicts, or peacekeeping efforts abroad. In contrast, DSCA is specifically tailored to national response strategies for emergencies that affect the civilian population within the nation's borders.
