Why coalition navies can cooperate effectively

Which Allied services worked best across national alliances?

He argues that navies often cooperated particularly well because ships and task groups are self-contained units rather than adjacent national front lines.

Coalition naval forces often find practical cooperation easier than armies because ships operate as relatively self-contained units. They can combine in a task group or coordinate separate groups without sharing a continuous front line. Land forces must negotiate national formation boundaries that an enemy can identify and exploit as weak points. Naval cooperation still depends on senior officers respecting one another, but the organisational geometry removes one recurring source of coalition friction.
