Which term describes the ability to relocate while preserving defense capability?

• A. Mass
• B. Mobility Deff
• C. Mix Deff
• D. Direct Support

Answer: (B)

Mobility defense is the ability to relocate while preserving defense capability. It combines movement with continuous protection, so units can shift to better positions or respond to changing threats without leaving gaps in coverage. This approach keeps overlapping fields of fire, sensor and communication links, and command and control intact even as forces relocate, which helps maintain the overall defensive posture.

Why this fits best is that it directly addresses the need to move and still defend—unlike a mass approach that concentrates forces in one area and becomes vulnerable when you have to shift, or a mix approach that may blend methods but doesn’t inherently emphasize maintaining defense during relocation. Direct support is about providing fires to other units, not about sustaining a defensive posture while moving.
