WASHINGTON (AP) — In the modern twist on old-fashioned war games, the U.S. military dispatched cyber fighters to Estonia this fall to help the small Baltic nation search out and block potential cyber threats from Russia. The goal was not only to help a NATO partner long targeted by its powerful neighbor but also to gain insight on Russian tactics that could be used against the U.S. and its elections.

The U.S. Cyber Command operation occurred in Estonia from late September to early November, officials from both countries disclosed this week, just as the U.S. was working to safeguard its election systems from foreign interference and to keep coronavirus research from the prying reach of hackers in countries including Russia and China.
