Never a finer tactician has the Imperial Guard ever seen than that General Creed, let me tell you. He came up with plans so devious and cunnin' you didn't even have a hope of figurin' out how he'd done what he'd done 'less he explained it to ya himself. We were fightin' on Kavara IV, what'd used to be a good Imperial world till the taint of Chaos found its way down there and turned loyal citizens into traitorous scum. At the time we'd been shipped off, we thought we were just gonna be helping the local PDF put down a small insurrection, but what with the ways of the warp by the time we got there it'd turned into a full on rebel uprisin' and all the nobles were already dead or in hidin', and another army led by General Creed had arrived to bring it back under control - we'd been missin' so long they thought we'd been lost to the warp, you see, and sent another off in our place - so we wound up joinin' forces an' bolsterin' their ranks.
Now, we got deployed into one of the urban centres that'd been taken over almost entirely by the heretics, goin' through clearing buildings of resistance and tightenin' the noose around their filthy necks. Only been gettin' minor resistance until a couple of hours in, when we stumbled across a fortified plaza that hadn't been in none of the intelligence reports. So there we were, pinned down by enemy fire, usin' rubble for cover and hopin' to the Emperor that'd we get some artillery support soon, when all of a sudden there's a tremendous rumblin' off to the right, soundin' like a column of tanks comin' up towards the buildin' we'd just cleared.
