A soldier stands guard as a policeman searches men for drugs and weapons during an operation in San Salvador January 23, 2012. As Mexican cartels are moving into Central America, this forces governments to call in army troops to support local law enforcements efforts against drug trafficking. Drug gangs have also established connections with local kingpins and gangs, known as Maras, increasing the levels of violence in the area. Picture taken January 23, 2012.
