We had an OPS Officer who came from the ORSE Board. Not well liked, as you might imagine. He and the Engineer had doors on their staterooms. As we left on a patrol, the door to the OPS stateroom disappeared. OPS, claiming that it had to be guarded as it contained classified information, insisted on a guard be posted 24/7. After a couple of days, the CO told him to knock it off. He was sure the crew had stolen it. The chiefs told him that the officers had it.
At the end of the patrol, the door was found under the mattress in the second bunk in the XO's stateroom.
