US operations at RAF Mildenhall in Britain will end as part of a money-saving consolidation plan that will result "in a slight decrease in our force levels" in the region but no loss to American military power, the Pentagon said.
Despite the closure of Mildenhall and smaller outposts elsewhere including the withdrawal of 500 troops from Lajes Field in Portugal the United States remains committed to its European allies, Pentagon chief Chuck Hagel said.
Some of the forces withdrawn from Britain, Portugal and elsewhere will be shifted to Germany and Italy, officials said.
The moves will mean a net decrease of about 2,000 US military and civilian personnel in Britain, while in Germany, the American military presence will increase by several hundred troops over the next several years.
The Pentagon said the reorganisation will save the US government about USD 500 million a year and enable a more efficient use of resources.
