CNN.com: U.S. troops detail fierce fighting in Afghan campaign

I'm reminded of the movie, Starship Troopers (official site). They underestimated their enemies, too.

I remember seeing a documentary on PBS about the Soviet-Afghan war (which went on for nearly 20 years)... it's not as if the Soviets were pushovers. They faced the same problem as we do now... fighting warriors who know how to fight in those mountains and caves.

Lovely.
