Strategic Thinking:US Marines Increasing Presence in Norway

One of the main events for US Marine Forces Europe and Africa this summer was the augmentation of its rotational presence in Norway,at the request of the Norwegian government as stated in a bilateral document.This provides for:
1.More than doubling the number of Marines from about 330 to 700;
2.Establishing a second rotation of Marines in Trom County,Northern Norway,around 250 miles from the Russian border;and
3.Extending the programme for another five years.
The programme began in 2017 with a rotation in Central Norway's Trondheim area,some 900 miles from the Russian border.In a crisis,these troops could be rapidly shifted to Sweden as a Baltic reinforcement.
Besides troop rotations,the Marines have been prepositioning military equipment in the Trondelg area under the Marine Corps Prepositioning Program-Norway (MCPP-N).The MCPP-N is intended to supply a full Marine Air-Ground Task Force (MAGTF) or Marine Expeditionary Brigade (MEB) for 30 days if bolstered with additional supplies.There are 6 caves and 2 storage facilities near air bases in this Central Norway location for Marine Corps vehicles and other gear.The exact locations are classified;but the stated purpose of the caches is to support global operations.
The Marines also utilise the Maritime Prepositioning Force (MPF),storing their gear on ships.The gear is used for exercises in Northern Europe and Theater Security Cooperation Events,as well as being on hand for crisis response.*
Most of the Marines are based near Trondheim;under the new agreement,an undisclosed number will rotate to the Arctic Trom region.Indeed,even those in Central Norway have concentrated on acquiring Arctic warfighting skills.Norway is very concerned about Russia's Arctic activities,since Norway's land border with Russia is in the Far North;as well,Russia's Northern Fleet transits the Barents Sea,including ballistic missile submarines armed with ICBMs.*
In strategic circles,it is commonly believed Russia might launch a surprise ground attack on the Baltic States,fortified with its anti-access/area denial advantage from its ballistic missile,air power and surface-to-air defence assets in the Russian enclave of Kaliningrad,which is located between Poland and Lithuania on the Baltic Sea.
This scenario could also entail a quick strike on Sweden's Gotland Island to establish a second Baltic A2AD chokehold,so the Marines have done some training on Gotland,during the Aurora 17 drills.
