David Vergun at the DOD News offers the below piece on the Defense Department's counternarcotics mission:
The Department's statutory mission is to serve as the single lead agency for the detection and monitoring of the aerial and maritime transit of illicit drugs into the United States, another Defense Department official, Matthew J. Flynn, deputy assistant secretary of defense for counternarcotics and global threats, explained.
One priority of the strategy is to reduce the availability of illegal drugs in the United States, Flynn said. "By performing this priority mission, DOD helps deter, disrupt and degrade potential threats before they reach the United States and harm our citizens," he said. With help from DOD, federal agencies — such as the Coast Guard, the Drug Enforcement Administration, Customs and Border Protection and others — are enhancing their efforts focused on the interdiction of heroin, cocaine, fentanyl, methamphetamines and precursor chemicals in the air and maritime approaches to the United States and along its borders. Flynn said the DOD aims to reduce the harm posed by criminal networks. "Through our programs, we disrupt and degrade drug trafficking and other illicit threat networks, in order to reduce them to a level where they no longer threaten United States citizens and U.S. national security," he said.
