Because CBS was worried about all the navy-obsessed fans of JAG buggering off to other channels, Season One dealt with cases that actually concerned the Navy. However, once these fans had been safely harvested, CBS realised they could just go ahead like any other cop show and squash the occasional marine or dogtag into the odd case. They also realised something was needed to define them, so someone came up with actually revealing to the viewers the outcome of the case without all that tedious watching: before the episode starts, there is a sound like a duvet being hit and the screen shows a black and white image of some members of the NCIS team looking distressed or some poor sucker's mangled corpse. Episode continues normally until it reaches this point in time, and the greyness returns.
