Comparative Command Echelons
Units and Commanders

This resource illustrates the typical chain of command and unit designations among the various military services, to facilitate cross-service comparisons. Given the diversity of unit designations some formations are not included for the sake of clarity. The rank of the officer commanding the unit, as well as the unit strength, are typical for units most commonly encountered, and considerable variation exists in practice, particularly with respect to intermediate echelon Naval forces.
