Which statement best describes the role of static defense in PLA doctrine?

• A. It is used to achieve immediate decisive victory
• B. It is used to achieve rapid breakthrough
• C. It relies on aerial bombardment for effectiveness
• D. It is not decisive and supports broader actions by delaying and buying time

Answer: (D)

Static defense in PLA doctrine is about delaying the enemy and buying time for larger operational goals. It’s seen as a stabilizing, non-decisive phase that slows the attacker, absorbs the initial blows, and disrupts tempo so that forces can be mobilized, reconstituted, and positioned for subsequent offensive or counter-offensive actions. The value lies in creating space and time for joint operations and for shaping the battlefield, rather than delivering an immediate, standalone win.

That’s why this option fits best: the role is to not be decisive on its own but to support broader actions by delaying and buying time. The other ideas misread static defense as the main path to quick victory or as primarily reliant on air bombardment; static defense can be part of a larger campaign, but its essence is slowing the attacker and enabling strategic/operational maneuver rather than forcing a rapid breakthrough or relying chiefly on aerial strikes.
