They patrol hundreds of miles of rugged terrain in bone chilling temperatures. Their "beat" includes an island less than two miles off the coast of Russia. And they fight crime in areas with more bears than bars.

They are the Alaska State Troopers—an elite law enforcement agency specially trained to serve and protect America's largest state.
