Gloves are off. The US Army steps firmly onto Marine Corps turf.

As it rethinks its global posture for a possible shift to the Asia-Pacific region, the U.S. Army wants to buy a new fleet of small boats and upgrade existing watercraft, an official said.
The land force and largest branch of the U.S. military has more than 100 vessels in its inventory — including the Cold War-era Landing Craft Mechanized-8 “Mike” boat, as well as the larger Logistics Support Vessel, LSV, and Landing Craft Utility, or LCU-2000 — to support combat and humanitarian missions.
The Army is gearing up to solicit proposals to replace the so-called Mike boats as part of a new acquisition program to buy three dozen craft called the Maneuver Support Vessel (Light), or MSV(L), according to Scott Davis, who heads the service’s Combat Support and Combat Service Support office in Warren, Michigan.

There is no such thing as a crowded battlefield, at least when you're talking about friends or allies.

THERE IS SUCH a thing as services stepping onto each others designated roles and functions.

100 New Mike boats?

During a time when the Army is having trouble getting funding for its Ground Combat Vehicles?

This might be bluff and bluster but its clearly a shot across the USMC's bow.  The gloves are off and they've stepped firmly into Marine Corps turf.  Is this in response to the SPMAGTF-CR's that Amos stood up?

Is it part of the chess game with the budget?

Unknown.  What I do know is that this will raise eyebrows in Marine Corps circles.
