The Campaign Ends at the Breach: Lessons from Ukraine on Why Armies Fail

A military campaign's success can be decided at the very first obstacle, as the inability to breach enemy defenses can halt an entire offensive before it truly begins. Ukraine's 2023 counteroffensive provides a stark lesson, where armored brigades sat ready but were unable to advance after engineers failed to clear a path through Russian minefields under fire. This critical moment is a recurring pattern in warfare, seen in both the successful Allied advance after securing the Remagen bridge and the failure of Operation Market Garden due to stalled crossings. Consequently, military planners must treat breaching not as a simple engineering task, but as a decisive combined arms operation that can make or break the entire strategic plan.
