In 2017, the U.S. Army’s 2nd Cavalry Regiment stationed in Europe received the first batch of the improved or up-gunned—in military parlance—Stryker Dragoon armored vehicles. Commanders on the ground requested them, as the 2nd needed to improve its capabilities against near-peer adversaries in theatre. In Europe, this likely would mean Russia.

The term adversary is typically reserved for real foes. According to the official Department of Defense Dictionary of Military and Associated Terms, an “adversary” is “A party acknowledged as potentially hostile to a friendly party and against which the use of force may be envisaged.” However, according to The War Zone, “adversaries” is also a term used by U.S. armed forces to describe “surrogate opponents during an exercise.”

It’s therefore worrisome that according to the Pentagon’s Office of the Director of Test and Evaluation (DOT&E), the Strykers’ onboard systems had certain cyber vulnerabilities, which Russia disrupted on at least one occasion.
