Amphibious operational effectiveness is related directly to the degree to which one commander has authority over all parts of the naval expeditionary force-the "Iron Law" of unity of command-and that one commander should be Navy.
Strolling in the garden of naval amphibians, we can spot both fruit and various threats to its successful harvest. From one vantage point, we see the seeds of progress creating a modern amphibious doctrine called operational maneuver from the sea (OMFTS) and the tools to support it. We also see the germination of a Navy concept called operational maneuver at sea (OMAS)-the application of maneuver warfare to naval operations at sea in a joint campaign. From another, however, we can glimpse the gathering storm of Marine parochialism scheming to control naval power. We also catch the gathering storm of Navy patronage pretending to support its sister service and the gospel of amphibious warfare. The fear is that one (or more) of these gathering storms may break sometime soon and erode our capability to project rapid and decisive power ashore.
