In the most expensive initiative in Latin America since the Cold War, the U.S. has militarized the battle against the traffickers, spending more than $20 billion in the past decade. U.S. Army troops, Air Force pilots and Navy ships outfitted with Coast Guard counter-narcotics teams are routinely deployed to chase, track and capture drug smugglers.

The sophistication and violence of the traffickers is so great that the U.S. military is training not only law enforcement agents in Latin American nations, but their militaries as well, building a network of expensive hardware, radar, airplanes, ships, runways and refueling stations to stem the tide of illegal drugs from South America to the U.S.
