Drookian Fen Guard
Winners of the coveted Imperial Guard Silliest Name contest for 400 years straight.
The Drookian Fen Guard hail from the planet Drook VI. It's pretty much SCOTLAND IN SPESS. The Drookians are big on CLAN HONOR and all that jazz; as such regiments raised from the planet all consist of members of a single clan. They are no big fans of outsiders telling them what (not) to do, not unlike the Catachans. Unlike the Catachans however the Commissars assigned to the regiments motivate the troops by telling them that the enemy has wronged fellow clan members (which may or may not be true), which gets them to haul ass fast so they can kick the enemy's.
