The Jongrinsb Theater was an area of operations in the Tarsian War.

During the Todfrey Campaign of Nikkr-Br, the Angosian soldier Roga Danar saw combat experience as a member of the Marvhil Infantry Division in this theater.

In 2366, this theater was mentioned in Danar's military service records, which were accessible to the crew of the USS Enterprise-D via the Angosian senatorial database. (TNG-R: "The Hunted", okudagram)

The theater is named after Jon Grinsberg, editor at CBS Digital, who worked on the remastered TNG project.
