HOOAH! Bar

The HOOAH! bar (now known as Soldier Fuel) is an energy bar created by the United States military in 1996. It was originally provided to military personnel packaged within a field ration, such as the Meal, Ready-to-Eat, Meal Cold Weather, or First Strike Ration.

The name comes from the word "hooah," a battle cry commonly used by American soldiers, also noting that Marines tend to prefer the word "Oohrah!" on the packaging. The bar originally had "HOOAH!" and the US Army seal on one side and "OOH-RAH!" and the US Marine Corps seal on the other; the new wrappers have both logos on the same side. The commercial version features the United States roundel instead.

The original military HOOAH! Bar came in apple-cinnamon, chocolate, cran-raspberry, peanut butter and raspberry flavors. The smaller First Strike bars (provided in the concentrated First Strike Ration) come in apple-cinnamon, cran-raspberry, chocolate, raspberry and mocha flavors.

Commercial availability
In 2004, D'Andrea Brothers LLC licensed "HOOAH!" for commercial sales, and the company started marketing the bar to the public in 2004. The energy bar is now named "Soldier Fuel" instead of HOOAH!, and provides 270 to 280 calories, 10 grams of protein, 8 or 9 grams of fat and 40 grams to 42 grams of carbohydrates.
