From Warhammer 40k - Lexicanum
- The 10th Logres Regiment, led by Colonel Octavius Rabelaq, took part in the Battle of Tarsis Ultra when the planet was attacked by a tendril of Hive Fleet Leviathan. Though the planet was saved and the 10th survived the battle, Colonel Rabelaq, commanding the regiment from a Capitol Imperialis, would perish in a heroic act of self-sacrifice, preventing the 993rd Death Korps of Krieg Regiment from being overrun during a rearguard action.
- Unknown regiments are known to have protected Krill farmers from the Tarellians.
