Which tactic is effective in ensuring that defense positions maintain mutual support?

The effectiveness of ensuring that defensive positions maintain mutual support is best achieved by positioning units where they can cover one another's vulnerabilities. This approach enhances the overall strength of a defensive setup by creating a network of interlinked positions that provide overlapping fields of fire and support. When units are strategically placed to cover each other's flanks and critical areas, they reduce the risk of a gap being exploited by an enemy attack.

By aligning defensive positions in a way that each unit can support neighboring units, the defense becomes more robust. This mutual support allows for coordinated responses to threats, enables effective use of available firepower, and can create a psychological deterrent for the enemy, knowing that they will face multiple layers of defense.

In contrast, spacing defensive positions widely apart would result in isolated units that could be easily overwhelmed or bypassed, while avoiding supporting fire would leave units vulnerable at critical moments. Concentrating fire solely on one location would diminish the overall defensive capability, as it could create opportunities for the enemy to exploit weaknesses in other areas. Thus, the rationale behind positioning units for mutual support is a crucial tactic in effective defensive operations.
