President Joe Biden issued an executive order approving the mobilization of select reserve forces with up to 3,000 personnel, augmenting the armed forces in support of Operation Atlantic Resolve.

President Biden issued an executive order mobilizing up to 3,000 reserve forces to support U.S. European Command in Operation Atlantic Resolve, which aims to defend NATO’s eastern flank amid Russia’s invasion of Ukraine. The mobilization will designate the operation as a contingency to provide benefits and entitlements to troops. A Eucom spokesman said the increased authorities will ensure resilience in their operations without changing current force levels in Europe. The spokesman stated the mobilization demonstrates U.S. commitment to allies and partners while giving Eucom flexibility to provide entitlements to supporting forces. An official noted that despite facing difficult conditions, Ukrainian forces are performing remarkably well with new equipment and tactics.
