The 1st Cavalry Division Artillery, also called The Red Team, was preparing Wednesday for a multinational exercise in Europe.
Operation Saber Guardian kicks off July 11 and ends July 20.
The exercise will involve 14,000 American troops in Bulgaria, Hungary and Romania. When participating service members from more than 20 ally and partner nations are factored in, there will be more than 25,000 troops involved in the exercise.
The operation's goal is to improve readiness and operability under a unified command, in an effort to better protect and stabilize the Black Sea Region.
