"At the end of the day, though he's been ferried through hell on a ship that's ten thousand years old to some godforsaken, war-torn rock; though he deployed from high orbit with nothing but a grav chute; though he is one of ten million men and women snatched from his homeworld to fight a war he barely understands; though he has been given a weapon that fires small suns and may annihilate him as he fires because the knowledge of how it functions has been lost; though his company is supported by tractor-tanks that run on anything you can burn; though he wages war against a devouring hivemind, ravenous demons and hordes of hyper-advanced aliens with strange technologies and sorceries he never dreamed existed; no one will remember his sacrifice, there will be no records of his deeds, no glorious parades in his honor, and no remembrance of his name. All he will earn is a shallow, unmarked grave on a forgotten world untold lightyears from home.
Yet for all this thankless sacrifice a Guardsman is a man, just like you. He has no millennia-old genetic engineering, no prophetic leader, no miracles of faith. He has his lasgun, his orders, and those beside him. He is the Imperial Guard.
And he will hold the line."
