When an Army Service Component Command (ASCC) is in support of a Geographic Combatant Command (GCC), it is designated as which?

• A. Theater Army
• B. Joint Task Force
• C. Army Component Command
• D. Field Army

Answer: (A)

When the Army’s service component operates within a Geographic Combatant Command, its theater-level designation identifies it as the land component for that GCC. That specific term is Theater Army, signaling that the Army forces in that geographic theater are organized and commanded to support the GCC’s operations in that area. A Joint Task Force is a temporary joint organization under a JFC for a particular mission, not the standard Army land component of a GCC. Army Component Command is the generic label for an ASCC within a GCC, but the theater-level designation used in this context is Theater Army. Field Army is an older, larger formation term and isn’t the designation used for the ASCC within a GCC today.
