"Lieutenant Sevens' log, stardate 41012.9
"I have come aboard the ship finaly and met the captain, who appears to be a fine individual. Shortly after I arrived we performed a brief test launch with me manning the tactical station. It was largely a success even with a slight shielding malfunction and some apparent minor friction between the captain and a medical officer. At the end of the test, he assigned me to the position of Chief Tactical Officer. I don't know if this position also entails me being in charge of security, at least until a Chief Security Officer is found, but I intend to ask him when I have a chance. End log."
"I am told that in Starfleet there is no 'tactical' position, only a bridge station. I am, therefore, Chief Security Officer. End edit."
