In PLA defense, which phase is 'Build the command system'?

• A. Spoil the enemy's preparations
• B. Counterattack
• C. Build the command system
• D. Consolidate or withdraw

Answer: (C)

The phase centers on establishing a unified command and control framework for the defense. Building the command system means setting up clear command relationships, robust communications, and integrated information flow so that decisions, orders, and actions can be coordinated quickly across all forces and support elements. This is essential because defense is a dynamic effort: you need timely situational awareness, rapid decision cycles, and synchronized actions to respond to changing enemy moves and to allocate resources effectively.

That’s why this phase fits best. The other options describe actions that depend on having a solid command backbone: spoiling the enemy’s preparations is about preemptive disruption, consolidating or withdrawing is about stabilizing or retreating when needed, and counterattack is an offensive move that comes after defense is in place and conditions allow. Building the command system is the foundational step that enables the rest.
