Which action denotes creating a passage through an obstacle for friendly forces?

• A. Block
• B. Canalize
• C. Contain
• D. Breach

Answer: (D)

Creating a passage through an obstacle for friendly forces is breach. It involves opening or removing a gap in obstacles like walls, fences, minefields, or fortified positions so troops can move through. Breaching is typically accomplished by engineers using explosives, mechanical tools, or specialized techniques to create a traverse for the assault force, often supported by suppression or reconnaissance to ensure the path is safe to pass. This differs from blocking, which aims to stop movement; canalizing, which directs movement along a chosen route without removing the obstacle; and containing, which is about holding or restricting something within a boundary rather than opening a passage.
