Star Blazers - Season 2 Episode 7 Sub-space Submarines

The Space Marines cause a flurry of problems for the Argo's crew, including disrepecting Nova's authority and literally creating a mess in the mess hall. Two sub-space submarines from the Comet Empire then attack the Argo. The Star Force destroys the submarines, but they still don't know what kind of enemy they are facing. Sandor has the ship land on a planet so the damage can be repaired. Meanwhile, the Argo's crew and the Space Marines get into a brawl and Wildstar and Sergeant Knox, the Space Marines' leader, get into a fist fight, which Dr. Sane breaks up. Dr. Sane says that Knox has to adjust to not only having been defeated at Brumas, but also to having had to relinquish command to Wildstar. On the Argo's bridge, the crew receive a garbled message from Telezart, but they are able to at least extract navigational coordinates from the message. The Star Force sets course for Telezart.
