Abstract: A keyboard for use with a computer is disclosed. The keyboard has an array of keys made up of four rows such that all keys are accessible by a user using finger and thumb movements of the user's hands without moving the hands from a central location. All modes and functions of the keyboard are accessible using finger movements also in that the character keys on the keyboards are capable of producing different characters or performing different functions when actuated in combination with other mode and function keys on the keyboard. The keyboard has a space bar and an enter key that are accessible by the user's thumbs. The space bar and enter key are actuated by pressing either key horizontally rather than vertically as in standard keyboards. The keyboard also includes dual mode keys which allow the user to access additional modes. This feature expands the capability of the keyboard to interact with more software functions.

Moreover, the nose plate is hardened steel specially designed to cause ripping and tearing of the exterior wall as the warhead penetrates.
