RESET: Russian Military Forces Staging Near Ukraine.

As many as 40,000 Russian troops, including tanks, armored vehicles, and air force units, are now arrayed along Ukraine’s eastern border with Russia.

Additionally, large numbers of Russian military forces will conduct exercises in the coming days that Pentagon officials say could be used as cover for an attack on Ukraine.

“Russian units will likely practice reinforcing the [Crimean] peninsula through such activities as amphibious landings and air defense exercises, and this may involve the change out of equipment and long convoys of military vehicles,” one defense official said.

The military exercises are an ominous sign. Similar large-scale Russian exercises were conducted near Ukraine a month before Moscow carried out the covert military operation to take over the strategic Black Sea peninsula in March 2014.

Moving that many units around is expensive, even without a fight. Clearly Putin expects to get something out of the effort.
