He recently co-authored an article with Michael Kofman at the Washington Post titled, "Here’s what we know about Russia’s military buildup near Ukraine."

This translates into roughly 48,000 troops. Adding the supporting units, the total number of Russian troops is likely to be 85,000 — with more on the way.
