4th Regiment was an Imperial Army formation based in the city of Tiems during the Galactic Civil War. 4th Regiment fought in the Battle of Tiems, where it was held in reserve to exploit any breakthroughs. When Alliance forces fell back along the Tiems Road, 4th Regiment followed 2nd Regiment and was caught in a trap by other Alliance forces that almost completely destroyed the unit.
It is unknown if 4th Regiment was the official name of the unit, or whether it was simply an identifier used by the Alliance for debriefing purposes.
