Russian army will deploy 3,000 soldiers and 9 regiments of S-400 missile systems in Arctic region_.

A total of nine S-400 regiments are expected to be deployed by Russia across the Arctic in the coming months.

The S-400 Triumph SA-21 is a long range surface-to-air missile systems produced by Russian defense Company Almaz-Antey. The S-400 Triumph is intended to engage, ECM, radar-picket, director area, reconnaissance, strategic and tactical aircraft, tactical and theatre ballistic missiles, medium-range ballistic missiles and other current and future air attack assets at a maximum range of 400 km, and a altitude of up to 30 km.

The inclusion of heavy aerial defenses in the Arctic coincides with Russia's push to further militarize three crucial geopolitical frontlines — the Arctic, Crimea, and the exclave of Kaliningrad — as part of a new and ambitious military doctrine.

Military expansion in the Arctic has been a major Russian objective for the better part of the last decade. This special focus on the region is aimed at ensuring access to potential energy resources on the Arctic sea bed while countering anticipated Danish, Norwegian, Canadian, and US claims.

Moscow has undertaken a construction blitz across the Arctic in order to maintain Russian military superiority in the region. Russia is constructing ten Arctic search-and-rescue stations, 16 deepwater ports, 13 airfields, and ten air-defense radar stations across its vast Arctic coast.

As part of this policy, Russia began moving troops towards a new military installation 31 miles from the Finnish border. As of Jan. 13, 800 out of the proposed 3,000 servicemen had been moved to this new base.
