Seize the terrain surrounding the breach site to prevent enemy counter-attacks.
The document acknowledges that the Fulda Gap is gone. Chapter 4 dives deep into and Heavy Wooded Terrain .
The U.S. Army Infantry School has incorporated these tenets into its curriculum, referencing ATP 3-90.4 for the tenets of breaching operations alongside other manuals for movement formations and fundamentals of breaching.
Conducted to protect friendly forces, installations, routes, and actions within a specific geographic area. atp 3-90.4 pdf
Imagine your CAB (2 tank companies, 1 mech infantry company) is conducting a .
When an obstacle cannot be bypassed, units must execute a synchronized, combined-arms breach. ATP 3-90.4 outlines the strict synchronization required to execute this highly dangerous mission using the format:
In any future conflict, mobility operations will be contested. Enemy forces will actively disrupt crossing sites with indirect fires, air strikes, and electronic warfare. ATP 3-90.4 provides the doctrinal foundation for conducting these operations under fire — integrating movement control, counter-reconnaissance, and sustainment with the maneuver and engineer tasks that enable crossing. Seize the terrain surrounding the breach site to
Forces build and reinforce temporary infrastructure to facilitate rapid tactical deployment. This includes constructing ad-hoc combat trails, stabilizing mud-soaked terrain, and rapidly preparing forward arming and refueling points (FARPs) or landing zones (LZs) for rotary-wing aircraft.

The Combined Arms Battalion doesn't just win by shooting faster; it wins by thinking faster. And that thinking starts on page one of the PDF.
Field trains are responsible for crossing the gap and returning to the near side in coordination with the task force engineer and crossing area commander. This two-way flow of logistics personnel is essential for sustaining operations on the far side. Imagine your CAB (2 tank companies, 1 mech
