Polish soldiers from 18th Anti-Aircraft Regiment and U.S. Soldiers from 7th Army Training Center, check the launcher tube for damage after a counter-unmanned aerial system takes off near Lipa, Poland, Nov. 14, 2025. The intensive 20-day multinational Train-the-Trainer course rapidly qualified 20 students from Poland, Romania, and the U.S., most with no prior military drone experience, in a battle-tested C-UAS system through classroom, practical flight, and night operations, culminating in a successful live-fire demonstration to destroy a jet powered drone, thereby accelerating the fielding of this critical capability along the Eastern Flank Deterrence Line. As the battlefield evolves, we are leveraging U.S. experience and NATO authorities to solve problems for the Alliance. The training occurring at Lipa shows how Allies like Poland and Romania are rapidly procuring and employing systems that are battle-tested in Ukraine to strengthen the Eastern Flank Deterrence Line. This is the EFDL in action. (U.S. Army photo by Sgt. Luis Garcia, 52d ADA Bde)
