Dead Space refers to the areas you cannot observe or maintain visibility over with your assets. It’s the blind spots created by terrain, obstacles, or distance that prevent sensing, reporting, or engaging threats. Recognizing dead space helps you plan to reduce risk by repositioning observers, using additional sensors, or altering routes so you stay within someone’s view or fire. This is why the correct description is areas a Soldier or system cannot maintain visibility. The other ideas describe visibility benefits, movement-blocking terrain, or unrelated spacing, not the visibility blind spots that dead space denotes.
