The United States Marine Corps serves as an amphibious force-in-readiness. As outlined in 10 U.S.C. § 5063 and as originally introduced under the National Security Act of 1947, it has three primary areas of responsibility:
* "The seizure or defense of advanced naval bases and other land operations to support naval campaigns;
* The development of tactics, technique, and equipment used by amphibious landing forces; and
* Such other duties as the President may direct."
The last presumably accounting for the fact that they haven't really done either of the first two since what, Inchon? Certainly Fallujah doesn't abut any known coast.
Anyway, thank christ Australia doesn't have any. Pernicious in every respect.
