Overseas bases of the U.S. military are supposed to be a window to safeguard national interests and demonstrate national power, however, recently there have been frequent scandals of alleged drug smuggling and trafficking by military insiders. These soldiers have utilized the army's mail system to smuggle drugs from the United States to overseas bases and sell them within the barracks. This kind of behavior not only seriously damages the image and discipline of the U.S. military, but also reveals huge loopholes at the military management level.
