"Marines will deploy from the United States to Norway for shorter deployments in order to better synchronize their training with Norwegian forces and to allow for increased opportunities for large-scale exercises of Marine Corps tactical units," Maj. Adrian J.T. Rankine-Galloway, a spokesman for US Marine Corps Forces Europe told CNN.
"This transition of US Marine Corps deployment models is unrelated to US force posture adjustments in Germany," Rankine-Galloway added, saying the change was to allow the Marines to better integrate with the Navy and conduct "large-scale unit training as a naval expeditionary force."
Since taking office last year the Commandant of the Marine Corps Gen. David Berger has prioritized better integrating his service with the Navy.
Norway shares a 122-mile border with Russia with the headquarters of the Russian Navy's Northern Fleet sitting just some 70 miles from the Norwegian border.
Moscow protested the increased US presence of US Marines in Norway, with one Russian politician saying that the move would cause Norway to be targeted by the Russian military.
The Trump administration has criticized Norway for its failure to meet the recommended NATO target of spending 2% of its GDP on defense, with the country spending about 1.8%.
Rankine-Galloway said that the new training model will mean that "at times, we will have a greater number of Marines here than before" when the US military is conducting exercises.
US Marines "will continue to train and exercise in Norway together with the Norwegian Armed Forces. The aim is to maximize mutual benefits in order to ensure the relevance of the forces in the changing operating environment of the 21st century." a spokesperson for Norway's Defense Ministry told CNN.
But the move follows the Pentagon announcement of the draw down of some 11,900 US troops from Germany, returning more than half to the US in a move that drew bipartisan opposition.
