If the Pentagon gives its approval, Army ROTC courses here will be "liberalized" next year, Colonel Trever N. Dupuy, chairman of the Department of Military Science and Tactics, said yesterday.

The revamped courses will seek to give students an awareness of the connection between civil and military problems by compressing the standard technical material and allowing time for addition of such subjects as "The Policy of the United States" and "Missions of the Army."

University officials yesterday stated that all changes in the ROTC program would come from the individual branches of service. The Air Force is contemplating revisions similar to the Army's but details have not been announced. The Navy has expressed "interest" in the re-organization, but plans no action at present.

Started Last Year

Plans for an extension of the Army courses were formulated on an experimental basis last fall, when 18 hours of Military Science I and 13 hours of Military Science II were devoted to a consideration of changing concepts of war as expressed in the writings of classical military authors. The department intends to increase this to about 25 hours in both courses next year.

As conceived by Dupuy, the proposed revisions have two aims: to link specific military actions to the general principles of war, which remain valid regardless of technological changes; and second, to study the relation of the military to politics, both in war and peace.

A one term course based on the same material is currently being given at Princeton, but includes none of the technical material of military science courses. Dupuy feels that this meets only half the problem of training reserve officers.

Plans call for the introduction of a 20 hour section, "The Policy of the United States," in Military Science IV, and seven hours on "Missions of the Army" in Military Science III.
