To date, the U.S. has activated 14,000 troops for Europe. Half of those have mobilized unilaterally, including 4,700 82nd Airborne Division soldiers to Poland, 1,000 2nd Cavalry Regiment soldiers to Romania and 300 XVIII Airborne Corps soldiers to Germany.

Earlier this week, another 1,000 troops started moving out, including aircrew, maintainers and staff to support six Air Force F-35 strike fighters, 32 Army AH-64 Apache helicopters and 800 members of an infantry task force battalion to the Baltic states, Poland and Romania.


With the activation of the NATO Response Force, the U.S. expects to start attaching more troops to that organization, as part of a deterrence effort should Russia’s invasion of Ukraine threaten NATO territory.

“It’s a menu of options that are going to be available to national leaders,” Kirby said. “And again, what I can promise you is, as we get solidity on this, and more specificity, we’ll detail that.”
