Which units are part of primary force structure units within a PLA theater?

• A. Combined arms brigades, armored units, artillery, air defense brigades, navy fleets, Marine corps, air force units, Rocket Force units, and Strategic Support Force elements
• B. Infantry divisions only
• C. Space shuttle fleets
• D. Civilian contractors

Answer: (A)

The main idea here is that a PLA theater’s fighting power is built from a broad mix of primary combat units drawn from all services, organized to operate under a theater command. In the recent改革, ground forces are structured around modular combined arms brigades with integral support like armor and artillery, so those brigades form the core ground combat power within a theater. At the same time, naval power is provided by fleet formations (and the Marine Corps for expeditionary tasks), air power by air force units, and long-range strike capacity by Rocket Force units. The theater also relies on the Strategic Support Force for space, cyber, and information warfare, tying all elements together. This combination of ground brigades, armored and artillery units, air defense, navy fleets, Marine corps, air force units, Rocket Force, and Strategic Support Force elements represents the primary force structure the theater can bring to combat.

Infantry divisions, space shuttle fleets, and civilian contractors aren’t representative of the theater’s core fighting units, so they don’t fit as the primary force structure.
