Super snack.

Remember all that talk at the end of the Cold War about converting military technology to civilian uses? Well, bet you didn't think the "killer app" would be a candy bar.

The Hooah bar was created by the U.S. Army in 1996 to increase energy and improve performance of troops during intense military operations. But now gym-goers can chomp on the bars after a workout while soldiers are doing the same in combat.

Los Angeles-based D'Andrea Brothers LLC got the rights to start selling the silver, red, white and blue packaged bars commercially in flavors that include apple-cinnamon and chocolate crisp, according to the company's Web site. The bars may be similar to others on the market, but the Hooah has been tested to sustain three years at 80 degrees, making it suitable for a long life in an Army ration kit.

The term "Hooah" is a military exclamation for "heard, understood and acknowledged," and the bar that bears its name is available for about $1.50 online or at selected health stores around Los Angeles.
