What is one effect of implementing obstacles in military strategy?

Implementing obstacles in military strategy primarily serves to impose losses on enemy personnel and equipment. Obstacles can disrupt the enemy's planned movements and operations, forcing them to expend additional resources to either navigate around or overcome these challenges. This can lead to higher casualties and equipment loss as the enemy attempts to breach fortified positions, mines, or difficult terrain designed to slow their advance and create vulnerabilities.

By effectively placing obstacles, a military force can leverage its advantages, dictate the terms of engagement, and control the battlefield dynamics. While obstacles might impact troop movements or supply lines, their fundamental purpose is to create a disadvantage for the opposing force, leading to tangible reductions in their operational effectiveness through attrition.
