Russian Troop Movements and Tensions
Along the Ukrainian Border
Updated January 19, 2022
In mid-October 2021, social media and news outlets began reporting significant movement by Russian
military forces, with limited Russian transparency, on or near the Ukrainian border and within Ukraine’s
occupied Crimea region. These movements, which follow a similar military buildup in March-April 2021
and Russia’s Zapad military exercises in September 2021, have come amid increasingly aggressive
rhetoric reported from Russian policymakers about the so-called encroachment of NATO near Russia’s
borders and the geopolitical status of Ukraine. This rhetoric has continued despite new bilateral
negotiations between the United States and Russia, as well as joint meetings with NATO and within the
Organization for Security and Co-operation in Europe (OSCE), in January 2022. On January 14, Ukraine
was hit by a cyberattack that many observers attributed to Russia. That same day, the Biden
administration accused Russia of sending saboteurs to Ukraine “to have the option of fabricating a pretext
for invasion.” Many observers and policymakers, including some in Congress, have expressed concerns
about a possible new Russian invasion of Ukraine or other aggressive actions.
Russian Troop Deployments
Many analysts and officials characterize Russia’s recent military buildup as significant and as falling
outside normal troop rotations or military exercises, due to the deployment of units over long distances
and far away from their usual training grounds. Of particular concern is the movement and pre-
positioning of equipment closer to the Ukrainian border, which is difficult and time-consuming to
transport. Pre-positioned equipment allows Russian units to quickly mobilize and conduct operations.
One possible indicator of an imminent Russian operation would be the large-scale movement of personnel
to staff and operate pre-positioned equipment.

equipment and units (including Iskander-M Short

systems) from the 41st Combined Arms Army
(CAA) from the Central Military District,
headquartered in Novosibirsk, Siberia, to Yelnya,
on Belarus’s eastern border (see Figure 1).
On December 3, the Washington Post reported
that U.S. intelligence estimated the presence of
some 75,000 Russian troops near Ukraine and in
occupied Crimea and reported on Russian plans
that would involve the “extensive movement of
100 battalion tactical groups with an estimated
175,000 personnel, along with armor, artillery,

and equipment.”

Since that time, Russia has continued to build up
its forces in the region. Open source reporting indicates Russia has anywhere from 50 to 60 Battalion
Tactical Groups (BTG), near Ukraine or in occupied Crimea, and that number is likely to increase in the
coming weeks. Media reporting indicates Russia has moved helicopter and air assets, which are crucial to
support a potential offensive, closer to the border. Russia can also quickly mobilize and move Airborne
(VDV) and Naval Infantry BTGs to augment and spearhead its operations.
Analysts and media outlets have reported the movement of elements of the 1st Guards Tank Army (based
outside Moscow) and the 6th CAA (based outside St. Petersburg) to areas on Ukraine’s northeast border
near Voronezh. Reports also have noted the increased movement of units from the 49th and 58th CAAs
toward Ukraine’s southeast border and the Russia-controlled regions of eastern Ukraine. Troops from
Russia’s Southern Military District have conducted military exercises in occupied Crimea and have
moved artillery and BTGs into the peninsula. Some analysts are concerned Russia may be transporting
more landing ships to the Black Sea Fleet to support potential amphibious operations, although other
analysts are skeptical of the likelihood of amphibious landings.
Beginning in early January 2022, Russia has transported multiple BTGs, air defense, and artillery units
from its Eastern Military District and claimed their movement was part of a “sudden check of combat
readiness check.” Other media reporting noted the movement of support, logistics, and Iskander-M units.
On January 18, Belarusian and Russian officials announced these units would participate in joint Belarus-
Russian military exercises from February 9 to February 20 and would include air defense and fighter
assets. Some analysts are concerned Russia’s concentration of forces in Belarus and occupied Crimea is
intended to undermine Ukraine’s defenses by forcing it to divide its forces and guard against multiple
potential offensive points.
Russian Force Posture
These reinforcements add to an already robust and permanent Russian military presence established on
the border with Ukraine and occupied Crimea. Since 2014, Russia has created new units in the Western
and Southern Military Districts on the border with Ukraine. Russia also has created two new armies, the
20th CAA in the Western Military District and the 8th CAA in the Southern Military District, to oversee,
coordinate, and manage command and control of units transported to the border during a crisis or conflict.
In the Western Military District, covering the northern border with Ukraine and Belarus’s eastern border,
the 20th CAA (headquartered in Voronezh) is assessed to consist of two maneuver units: the 144th and 3rd
Motor Rifle Divisions. In the Southern Military District, Russia established the 8th CAA (headquartered in

Rostov-on-Don and Novocherkassk), which is assessed to consist of the 150th and the 20th Motor Rifle
Division. The 8th CAA also reportedly commands separatist units in Donetsk and Luhansk inside Ukraine.
Both CAAs have support, artillery, air defense, and electronic warfare units.
Russia’s military capabilities in occupied Crimea center on (1) the Black Sea Fleet and (2) ground, air,
and coastal defense units focused on defending the peninsula and denying freedom of movement to
Ukrainian and foreign actors. Observers consider Russia’s military forces in Crimea under status quo
conditions to be primarily defensively oriented. Russian ground forces are concentrated under the 22nd
Army Corps. Other units include the 810th marine infantry brigade and a new airborne regiment.
