Exhibit: Su-27 Flanker
The ground mapping radar is dead easy to use. Turn it on and slew it to the known target area, then zoom in - in - in until you can see the actual target, which may be an intersection, a building, runway, vehicle etc.
The target square in the cockpit display generates a diamond shaped cursor on your Heads Up Display. For unguided bomb delivery simply fly the round cursor over the diamond and release!
Note - I cropped this image to avoid pixellation.
