Panama is one of the hemisphere's most committed partners in the fight against narco-terrorists and cartels. These advanced drones enhance the capabilities of Panama and the broader Americas Counter Cartel Coalition to monitor remote regions and strategic pathways, intercepting dangerous traffickers at the source. #SOUTHCOM's funding of this delivery exemplifies our commitment to working with enduring regional partners to employ cutting-edge U.S. technology that outmatches those who threaten the Western Hemisphere and the American homeland. @USEmbPAN @MinSegPma Embassy Release: pa.usembassy.gov/u-s-expands…

On Sept. 15, under the direction of #SOUTHCOM, Joint Task Force Western Hemisphere (JTF-WHEM) forces successfully interdicted a floating refueling station supporting illicit at-sea drug trafficking operations in the Eastern Pacific. Intelligence confirmed the vessel's involvement with the Los Choneros violent narco-terrorist organization. Individuals removed from the vessel will be transferred to Ecuadorian authorities. After clearing the vessel and disembarking the crew, U.S. forces sank it. JTF-WHEM continues to conduct precise and professional operations to dismantle the logistical networks fueling narco-trafficking in the Western Hemisphere. "We are exerting unrelenting pressure on these narco-terrorists and hurting them where it counts: dismantling their intricate networks, disrupting their sophisticated logistics, and dealing a blow to their finances. This is what total systemic friction looks like." – SOUTHCOM Commander Gen. Francis L. Donovan #A3C #JTFWHEM @DeptofWar @SecWar @USMC @USNavy @USEmbassyEc @DefensaEc @The24MEU
