Lieutenant Barbara serves as a communications officer aboard the submarine 707 in the Peace-Keeping Navy. Operating during the conflict against the terrorist organization USR and Admiral Red’s forces, she relays critical tactical information and maintains contact with allied vessels during combat operations. Her role remains strictly operational, centered on her duties aboard the new 707 submarine following the destruction of the original vessel. The narrative remains focused on her professional function on the bridge, with no exploration of her personal history or motivations beyond her military capacity.
