Maneuver - correct answer ✔Maneuver allows defender to:
Take full advantage of Area of Operations
Mass and concentrate when desirable
Achieve advantage over enemy through movement and fires
Terrain Value to defense - correct answer ✔Utilizing terrain to play the advantage
Explore terrain because the enemy may know the terrain better and exploit it against
you
Mass and Concentration - correct answer ✔Defenders seek to mass effects through:
Overwhelming combat power in area of choice
Shifting combat power to support decisive operation
Retain a reserve to gain local superiority at the point of decision

Deception and concealment to hide force concentrations
Obstacles, security forces, and fires reduce risk where effects are not massed at
(Keep the enemy constantly moving through use of scouts and IDF. Letting them rest
allows them to plan and mass fire)

gaining momentum in the attack

arms to small range arms) while simultaneously destroying them with emplaced
obstacles

Analysis of terrain (geo-spatial)
Selection of positions that allow massing fires of likely Avenues of Approach
