One large helicopter grouping was spotted near the Belarussian town of Chojniki and contains more than 90 helicopters parked on a road with the deployment extending for more than five miles, according to Maxar’s images.

“Northeast of the town, a large deployment of ground forces with several hundred vehicles is seen in convoy position in several fields,” Maxar senior director Stephen A. Wood said in an email accompanying the images.

Another group of more than 50 helicopters, alongside support troops and equipment, was spotted roughly 40 miles away at the V.D. Bokov airfield near Mazyr, Belarus, Wood added.
