Which PLA-identified trend indicates that static defenses get bypassed, isolated, and annihilated due to dynamic operations?

• A. Increasing arduousness
• B. More dynamic
• C. Increasing importance of offensive actions within defense
• D. Static defenses get bypassed, isolated, and annihilated

Answer: (D)

Dynamic operations erode the value of fixed defenses by allowing attackers to bypass, isolate, and destroy them. In PLA thinking, speed, maneuver, and integrated fires enable forces to move around or through static positions, cut off their supporting links, and strike with precision, leaving fixed fortifications unable to hold or influence the battle. The trend described—static defenses being bypassed, isolated, and annihilated—directly captures this outcome of operating dynamically against prepared defenses. While other options point to shifts toward greater dynamism or the importance of offensive actions within defense, they do not express the specific consequence of dynamic operations on static defenses as clearly.
