What is the purpose of an obstacle plan in military operations?

The purpose of an obstacle plan in military operations is to manage terrain features and barriers against the enemy. An obstacle plan is designed to identify and utilize natural and man-made barriers effectively, creating obstacles that can slow down or stop enemy movements. This is crucial for protecting friendly forces and maintaining control over the operational area. By strategically placing obstacles, military planners can channel enemy forces into kill zones, protect critical assets, and enhance the overall defensive posture of friendly units.

Utilizing obstacles effectively requires an understanding of the terrain and how to best position barriers to leverage their defensive capabilities. The plan should consider factors like the enemy's likely avenues of approach, the types of obstacles that will be most effective, and how those obstacles integrate with other defense measures. By implementing a well-conceived obstacle plan, units can significantly impact the enemy’s operational effectiveness and improve their chances of success in combat operations.
