Sub Command Cheats

Select a mission at the mission window and advance
to the submarine selection screen. Use the mouse to place the
pointer on a submarine name and press [Tab]. You may now
use the mouse to click on the red arrow that is now active and
pick any submarine from the list.

In Mission window select the mission. Then on the sub screen is the sub you
have to use cause the arrow keys are in active and the player can pick any sub.
Well if you put the mouse cursor on the sub name and press tab, the arrow that
was in active turns red. The player can then take the mouse and click on the
red arrow that is now active and pick any sub from the list making it player's
choice instead of computer choice.
