'Border Wars' Nat Geo Channel Series Embeds Viewers Inside Real-World Battles Raging Across Our Borders

WASHINGTON, Aug. 18 -- An estimated 10+ million people live in the U.S. illegally. From the controversial border fence to controversial immigration laws, illegal immigration is hotly debated. For those responsible for securing our borders, protecting our nation goes beyond politics, as they intercept daily an illicit flow of narcotics, money and weapons. The risks have never been higher, with the violent Mexican drug wars a stone's throw from U.S. soil and criminals armed with increasingly sophisticated technology.

Premiering with a sneak preview Sunday, August 29, 2010, 9 p.m. ET/PT before moving to its regular night and time, Wednesdays 9 p.m. ET/PT, on September 1, Border Wars returns for a second season with 16 episodes of real-world pursuits, surveillance, interceptions, busts and rescue missions at some of the busiest and most dangerous border crossing points into the U.S., including in California, Texas and Florida. Ride shotgun with agents patrolling the Rio Grande, just across from the epicenter of violent cartel wars, where heavily armed criminals outnumber agents. See how ground and air units use the latest military-grade technology, including drones, thermal imaging and mobile cameras. And join agents as they raid stash houses to break up smuggling operations, or risk their own lives to save those close to succumbing to harsh weather and terrain. And, go behind-the-scenes as agents secure Super Bowl XLIV against terror threats, while patrolling Miami for human and drug trafficking.

Premiere episodes include:
