Army Aviation Captain's Career Course (AVC3) Entrance Practice Exam

Opening idea: When the path through an obstacle must be opened for maneuver, the unit conducts a breach. This action brings together engineers, infantry, armor, and supporting fires in a coordinated effort to defeat or remove the obstacle and create a corridor for follow-on forces to pass through. In a breach, engineers typically plan and execute obstacle reduction while adjacent maneuver units provide supporting fires, cover, and protection for the breach team. Once the obstacle is reduced or penetrated, the main body maneuvers through the created gap, continuing the operation. The emphasis is on integrating different arms to defeat the obstacle under the maneuver command so that movement through or past the obstacle is feasible and safe. Why the other options don’t fit as well: An assault centers on taking a position via direct attack, not specifically opening a passage through an obstacle with engineering and synchronized arms. Penetration aims to break through an enemy’s lines to gain depth, not primarily to clear an obstacle to allow through-mass movement. An overrun is a rapid seizure of an undefended area, without the coordinated obstacle defeat and passage through barriers that a breach requires.
