The Christian Science Monitor has an article on the changes in subject matter at the Army war college:

Some of the changes are as obvious as the addition of counterinsurgency and language electives to the curriculum. Yet at the most fundamental level, Fort Leavenworth's Command and General Staff College has had to reorient itself to stay relevant for veterans like Gardner, who come seeking to make sense of wars when tactics seem to change every hour.

Where once the college sought to instill its officers with the tactical know-how to defeat the Soviets, it has now turned to the challenging prospect of teaching soldiers how to think for themselves.

"It's a shift from a baccalaureate education to a master's-level education," says Brig. Gen. Volney Warner, deputy commandant of the college. "It's about developing in an individual the capacity to handle a broad range of problems."

In many respects, this is a task allotted to the entire military, as the uncertainty of today's unconventional wars calls for more thoughtful privates and sergeants, as well as officers. Yet some of today's majors will become tomorrow's three- and four-star generals, who help set the course and character of the Army. The Command and General Staff College, then, is something of a weather vane for the future of Army thought.

... The college has already added eight counterinsurgency-related courses, and students can now take electives in Arabic and Pashtun. In a dim hallway outside the main auditorium, a metal rack holds reams of suggested reading lists – but the slots for "cultural awareness," "counterinsurgency," and "militant Islam" have already been emptied.

In Gardner's class, tabletops teem with copies of "The Sling and the Stone" and "No True Glory" – officers' must-read texts on the nontraditional warfare of the new century. The topic for this day's seminar, too, is a twist on the traditional.

There is more. I disagree with the assertion that the US military hasn't been teaching officers to think for themselves. I have a clear memory of Basic School teaching the importance of thinking through a problem and coming up with a solution whether it was two up and one back or attempting an envelopment, or what kind of prep fire was needed on an objective. I think it has always been one of the differences we had with the more top down societies like the Soviets or Saddam's Iraq.
