Suddenly i get the feeling that the Imperial Army losses are just like those during the Crimean War.
Most men don't die because of the Enemy...nooo. They die of the Asbestos they wear. The Radiation coming off of their guns and vehicles. The Toxic Fumes expelled by whatever chemical and high-tech shenangigans they currently use.
Then there is the horrible food, the corpse starch and lets not forget that good part of imperial warfare consists of sieges that last decades. the sanitary conditions in the trenches of vraks must be horrifying.
So you survived all of that yes? Welcome to the field hospitals, where mechanics priests continue using aged equipmetn because its from the age of whateverthefuckwhocares, old rusted engines with rusted needles and knives.
You feeling sickly yet? How about rusted Ork Choppas. Tyranid Bio-Toxins, Whatever the fuck Dark Eldar coat their weapons in. Nurglitch influence off the battlefield, HIV and ten billion other bodily fluid infectious diseases stuck to blade of a khorne berserkers axe.
And now we know that Nurgle is mightier than Khorne because the longer Khorne Whorshippers fight the greater hte chance that they transmit diseases with their weapons.
Also the fumes from a baneblade, imagine one of the exhaust pipes malfunctioning and suddenly you choke on whatever the fuck they are fueled with.
And then the residue from meltas can't be healthy either to breath that shit in. Generally the sheer amount of a million guardsmen firing their lasers ought to cause global warming. And thats before some Space Mawines decide to Lance Bombard the Planet from Orbit.
Makes one wonder why everything isnt on fire.
