The command and control system of a division enables the division commander to
prioritize and allocate assets so as to employ and sustain combat power (page 3-
11, para 1g(1)).
The division engineer battalion has a primary role in mobility, countermobility,
and survivability operations (page 3-8, para 1b(4)).
The purpose of a cover is to provide the main body with early warning, reaction
time, maneuver space, and information about the enemy (page 3-6, para 1a(4)(d)).
The primary intent of countermobility operations is to attack the enemy's ability
to execute his plan by disrupting his combat formations...with an integrated
system of obstacles and fires (page 3-8, para 1b(2)).
