Proud to support global security efforts! Valiant recently delivered the Countering-WMD Security Cooperation Engagement Program (CSCEP) in Lithuania, strengthening partnerships and advancing critical capabilities where they matter most.
Partnership in Action: Bolstering Lithuania's Counter-WMD Capabilities The U.S. Defense Threat Reduction Agency (DTRA) is proud to partner with Lithuanian Armed Forces (LAF) in Kaunas. Our Building Partner Capacity team is transferring state-of-the-art Chemical, Biological, Radiological, and Nuclear (CBRN) equipment and conducting intensive New Equipment Training. This crucial initiative directly enhances the LAF's counter-weapons of mass destruction (CWMD) operational capacity, strengthening Lithuania's sovereign defense and helping our vital ally meet NATO capability targets. This collaboration sends a clear message of deterrence and reinforces our collective commitment to security on NATO's eastern flank. A more capable Lithuania means a more secure Alliance. #Partnership #Defense #CWMD #Lithuania #Deterrence #SecurityCooperation #WeAreNATO
