What is the role of the depth defense group?

• A. Full-scale decisive attack
• B. Harassing decoy operations
• C. Depth Defense Group
• D. Strategic bombing

Answer: (C)

In defense, operations are built in layers to slow and wear down an attacker while keeping your main fighting power intact. The depth defense group is the unit responsible for the deepest layer of that system. Its job is to hold and defend deep objective areas, organize fortified positions and obstacles, and coordinate with adjacent echelons to absorb the enemy’s breakthrough. By applying fires, terrain advantages, and maneuver, it degrades the attacker’s momentum and buys time for the rest of the defender to regroup. Crucially, it keeps a ready reserve for a counterattack at the right moment, turning a delayed defense into a potential decisive reversal.

This role contrasts with options that describe offensive actions or deception. A full-scale decisive attack is an offensive mission, not the function of a depth defense group. Harassing decoy operations are deception-focused and not the primary purpose of the deepest defense layer. Strategic bombing is an air-power operation aimed at destroying targets from above, not about field defense in depth.
