Fun fact: If you actually help the Guardsmen finish off the enemies that they are fighting in this level, they'll actually follow you up to the command relay that you need to secure. This is the only mission in Chaos Rising that they do that, though.
Kyras before Dark Crusade: Thule, bring the Blood Ravens to Kronus and purge the planet to protect the secret of our chapter. Carry out the order even if the Imperial Guard stand in your way. Blood Raven during Chaos Rising: Chapter master! Chaos forces threating our recruiting worlds. The Black Legion's commander even mocked us and the Emperor himself. Kyras: Just fall back. We don't fight with the Black Legion. If I'd be a Blood Raven I'd be like: bro, are you a heretic or a fuckin' coward?
Some are badasfully skilled (drop-troops such as stormtroopers or elysians, harakoni...), some are there to make the enemy run out of ammo and slam him with the sheer mass of bodies (death korps, vallhalans...) some are your modern day army in quality (cadians).
Thaddeus: We beat back the Tyranids, you will fare no better! Araghast: empty bravado will not save you strippling Me: big words coming from a "nobody" chaos lord with halfass megatron trope
@woodwyrm The Grey Knights Codex also the Tyranids attacking a planet while some daemons tried to turn it into a daemon world, but neither of them won since the planet was hit with an exterminatus.
@dragonstormx to Araghast, who may have lived for more than thousand years, such a claim is but hot air from the mouth of a loyalist. Perhaps he simply have never faced Tyranids before to realise their threat?
Not the Tanith, at any rate. They're more of a "sneak up behind you and stab you in the neck with straight silver while your buddies all get sniped to pieces" sort of Guard regiment.
Blabla, Aragast is some big headed Chaos lord that probably just won a few victories over a bunch of badly defended worlds. Really, what kind of idiot thinks a good response to beating a Tyranid invasion is calling it empty bravado?
