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.
