LA MACARENA, Colombia -- Seen from the air, the sweeping mountains of the Macarena jungle in Colombia's southern province of Meta stretch interminably towards the hazy horizon. The muddy Guayabero River snakes through this green land of deep canyons and forested valleys. It is here that Colombia's largest guerrilla group, the Revolutionary Armed Forces of Colombia (FARC), clings to its last stronghold.
Colombia's southern provinces are the front line in the U.S.-backed counterinsurgency campaign against the guerrillas, the site of daily clashes between government troops and the FARC. Looking down from above on the rugged mountainous terrain, it is clear why hunting the rebels down remains such a difficult task.
"The land is perfect for guerrilla warfare," said Brig. Gen. Alejandro Navas, head of OMEGA, a special force set up five years ago to eliminate the FARC. "It's like they were handed a gift from the devil."
