Total estimated end strength is therefore already north of 90,000 personnel. These figures do not include airpower, naval units, or additional logistical components that are likely to support this force. Russian-led forces in Ukraine's Donbas region might account for another 15,000 troops, but they have considerably lower combat effectiveness than Russian regulars.
The force gathered from other Russian regions largely consists of prepositioned equipment, but it is already sufficient for a military operation. There are indications that Russia has begun sending personnel. The current force is largely within the self-deployment range, which means they can move to the border in a matter of days once personnel arrive. Russia retains considerable force-generation potential and can surge units to the area on relatively short notice.
Publicly available estimates suggest Moscow might gather a force of 90 to 100 battalion tactical groups, together with reserves, and auxiliary forces for a total of 150,000 to 175,000 troops. The Russian military is not yet in position for such a largescale operation, but it could have the requisite forces and elements placed in the coming weeks.
