Biscuit composed only of flour, water, and salt. Can be light, flaky, and edible, or cooked so long, that it becomes hard enough that it cannot be broken with hammers, cars, etc. Used in al armies and navies until the late 19th century, especially in the Civil War, and in Navies.

We recieved our ten days rations of biscuits today.
