For the Marines, a New Commandant Sees a New Corps, in a New Era of Warfare
The Marine Corps’ new commandant, Gen. David Berger, is breaking china, figuratively, to enable the Marines to break China, literally, should a conflict erupt in East Asia. As the only service whose forces are mandated by law — three divisions and three air wings — the Marines have relied on their traditional hold over Congress
U.S. Army Research Uncovers Pattern in Progression of Weapons Technologies
Anticipating the technology and weapon systems of our future Army might not be entirely daunting, new Army research finds. Trends in the progression of weapon systems from the early crossbowman to a musket to a military tank might help predict our future systems, according to a new study to be published in the Journal of
