Pentagon Begins Transferring Ukraine Security Assistance Group Leadership to NATO Ally in One-Year Transition

BLUFFormal NSATU command will likely transfer to an allied officer within a year, but the retained US deputy slot preserves Washington's operational influence while offloading the leadership burden.

Lt. Gen. Curtis Buzzard relinquished command of the Security Assistance Group-Ukraine and NATO Security Assistance and Training for Ukraine to Lt. Gen. Guillaume Beaurpere during a ceremony at Clay Kaserne in Wiesbaden, Germany, on Monday, US European Command reported 1. Buzzard, who is retiring after 34 years of Army service, is stepping aside as part of a broader EUCOM reorganization that the command said will shift leadership of key elements of the Ukraine support mission to allies and free US resources for other priorities 1. EUCOM Commander Gen. Alexus Grynkewich said a European or Canadian officer will take command of NSATU within the next year, with an American officer serving as deputy, and that SAG-U will be dissolved once the transition is complete 1. Citing a US official and three people familiar with the plan, Politico reported, per relays from Ukrainska Pravda and Interfax-Ukraine, that the full handover to another NATO member could take up to a year and that US European Command will continue to participate through an American deputy 23.

Analysis
Lt. Gen. Guillaume Beaurpere's assumption of SAG-U and NSATU command from the retiring Buzzard converts a previously anticipated handover into an executed transfer, though EUCOM has not yet named which ally will eventually lead NSATU. A European or Canadian officer will likely take that command within the year, with a US deputy retained to preserve continuity as SAG-U dissolves. Grynkewich's burden-shifting framing signals Washington intends to keep leverage through that deputy slot even while ceding formal command, and the move sits inside a wider EUCOM drawdown that also reverted Army and Air Forces Europe to three-star billets, suggesting institutional retrenchment rather than a deliberate alliance capacity-building push. Confidence is high, based on concordant statements from EUCOM and NATO officials on timeline and structure, though corroboration remains broad but shallow across a small outlet set. European and Canadian ministries must now decide within the year whether to commit a flag officer and sustainment resources to lead NSATU.
