In the context of defense, what does “mutual support” refer to?

"Mutual support" in a defense context refers to the concept of units providing cover for each other's positions. This involves coordinating efforts to ensure that if one unit comes under attack, it can rely on neighboring units for reinforcement and protection. The idea is to create a network of support that enhances the overall defensive capability, making it difficult for an attacking force to isolate or overwhelm a single position.

The effectiveness of mutual support lies in its ability to create overlapping fields of fire, share resources, and enable units to cover each other’s vulnerabilities. When units can support one another, they enhance their collective defense, maintain operational flexibility, and improve their chances of repelling enemy advances.

By contrast, assisting allies in battle, supporting the commander’s vision, or focusing solely on communication between units do not capture the essence of mutual support in a defensive posture. While those elements can be important in military operations, they do not specifically address the critical tactical function of units covering and defending each other's positions in a cohesive manner.
