Colonel Brian Sawser, DCOS Engineer for US Army Europe and Africa, sat down at Combat Engineer and Logistics 2026 to break down NATO’s Eastern Flank Deterrence Line (EFDL), a framework designed to create a day-zero dilemma for adversaries through physical barrier systems, AI-enabled targeting, autonomous capabilities, and all-domain defence.
Colonel Sawser outlines how the EFDL complements national and regional initiatives such as Eastern Shield and the Baltic Defence Line, addresses counter-mobility challenges, and explains why 2026 is designated the year of execution for NATO, with a series of exercises, training events, and industry experimentation opportunities already on the schedule.
