NOT listed as a possible form of a Key Defense Point?

• A. Terrain
• B. Airfield
• C. Command/Network Node
• D. Key Unit/Leader

Answer: (B)

Key Defense Points are categories of critical defensive locations or assets that a force concentrates on to disrupt the attacker and shape the battle. In PLA doctrine, the forms a Key Defense Point can take include terrain features, command and network nodes, and key units or leaders. An airfield, while a vital asset, does not appear as one of the defined forms of a Key Defense Point in this framework. It may be a target or a protected asset, but the taxonomy specifically lists terrain, command/network nodes, and key units/leaders as the forms. Recognizing this helps remember why airfields are not a listed form, whereas terrain provides natural defense, control over critical command and control, and protection of decisive units or leaders.
