adding a few more regiments raised by house Austin sent to other parts of the reach. many of the other regiments were not unique. many of the penal legions were just an example of 3 or 4 identical legions raised, GM ruled that a barracks could carry 10,000 men and gear. a cargo hold was needed for armor or mechanized regiments. anyway here are a few more.
the 45th Quppa-psi calvary
homeworld: Quppa-psi/ jungle world/ koronus expanse
military speciality: air calvary/ beastmasters
order of battle: 5 companies of calvary 1000 men each, and 5 companies of beastmasters about 5000 men, each with about 10 whippers
commanding officer: Hassen Shellite, gets the job done whatever the cost.
history: after being saved from the maiden world known as the dread pearl, the sanctarch refugees were taken to Quppa-psi to resettle. many died in the first years as they learned to adjust from a carefree life on a world that gave them everything to one almost a death world. after several years the population learned to domesticate some of the more deadly lifeforms. as the population grew House Austin raised a regiment from this world.
miscellaneous: the calvary ride into battle strapped to the enormous dragon hornets of quppa-psi. the size of a lighter this huge insects have a entire squad strapped to their backs. mounting 2 forward facing lascannons and one "tail gunner". other troopers can fire their weapons from the sides, careful to miss the wings. the hornet itself is also a trained war beast, it's jaws able to tear through armor and it's tail stinger able to punch through the side of a tank.
dragon hornet: type: skimmer, speed: around 100 kph, manoeuvrability: +30, wounds 80, size: enormous, armor: 2, traits: skimmer, opened topped crew: 1 "driver", 3 gunners, 3 loaders, 1 commander carrying capacity: 4 guardsmen + wargear. weapons bite 2d10+8, sting 1d10+10 toxic, 2 forward mounted las cannon (use same as mounted on leman russ tank), one tail lascannon.
where the calvary used the dragon hornet, the beast masters used a different insect from Quppa-psi. the whipper. large pack hunting ambush predators, they proved to be much like dogs in personality and size when raised from eggs. each man can handle about 10 of these creatures sending them into battle in vast hoards. it's not so much that each one is that dangerous, they simply overwhelm the enemy with shear numbers. losing these creatures in battle isn't much of a problem either, like most insects they lay large numbers of eggs and mature quickly.
