AP 12/31 WASHINGTON (AP) -- The chairman of the Joint Chiefs of Staff believes the military services should operate under a single command when dealing with regional crises, according to Pentagon sources. The sources said Wednesday that Gen. Colin Powell is recommending that such forces be consolidated under the U.S. Atlantic Command in Norfolk, Va. -- and not necessarily be commanded by a Navy admiral as is the case now. The report, ordered up by Congress, also envisions the new command taking charge of any U.S. participation in United Nations peacekeeping missions and overseeing disaster relief efforts, said the sources, who spoke on condition of anonymity. The report has gone to Defense Secretary Dick Cheney and commanders around the world for their comments. It is to be written every three years to provide an updated review of the roles and missions adopted by the various branches of the armed services. However, Powell's latest version lacks the sweeping revisions endorsed by President-elect Clinton and key Democrats in Congress, the sources said. It "contains recommendations on the redistribution of certain types of military assets" but no major realignment of the military branches, said one source. Another official said the report "is consistent" with Powell's past calls for some readjustments. "I didn't find a lot of sweeping changes here." Cheney has told reporters he might let his successor in the Clinton administration deal with the final report and send it to Congress. President-elect Clinton's nominee for defense secretary, House Armed Services Committee Chairman Les Aspin, D-Wis., has called for far deeper cuts in defense spending than Cheney and Powell want, including reducing the size of the Army from 12 to nine divisions. Sam Nunn, D-Ga., chairman of the Senate Armed Services Committee, has recommended consolidating the air units of the Army, Navy and Marine Corps under the Air Force. The draft report turns that and several similar suggestions aside, said one source. Powell has defended the current air defense structure, saying each service's air component served the nation well in the Desert Storm war with Iraq. Instead, the source said, the draft holds to Powell's long-stated views that duplications should be eliminated in such areas as basic flight training and support functions. The report also includes at least one new proposal likely to draw flak in Congress: According to The New York Times, Powell wants to eliminate 10 Air National Guard jet fighter squadrons operating from 17 domestic bases.
