Two men who forged deep bonds of friendship while serving in the U.S. Army in Afghanistan drove an SUV packed with rifles and explosives from Florida to Texas, where they would be arrested in 2018. Their scheme involved stealing weapons and explosives from an armory at Fort Bragg, North Carolina, and trying to sell them. An Associated Press investigation into lost and stolen military weapons has shown that insider thefts remain a serious concern. (AP Photo/Patrick Semansky, File)
