What are convoys used for in a military context?

In a military context, convoys are primarily used for escorting passenger or supply ships to ensure their protection as they travel through potentially hostile waters. By grouping several vessels together and providing them with military escort, the risk of attack by enemy forces is significantly reduced. This tactic was especially crucial during times of war, such as World War I and World War II, where supply lines were vital for maintaining military operations. The logistics of moving troops, equipment, and supplies securely to where they were needed depended heavily on the effectiveness of these convoys to safeguard against enemy attacks.

While transporting troops to the front line might involve similar principles of protection, it's more specific to the movement of personnel rather than the broader activity of securing cargo ships. Delivering messages under enemy territory and conducting air strikes are distinct military operations that do not involve the concept of convoys, which are specifically focused on maritime transport and protection. Thus, the role of convoys as escorts aligns closely with the need for enhanced security during transport missions.
