I have to disagree Katharon, these aren't nearly the hardcore options that could be taken. If he wanted to cheese it up, he could've gone with standard Space Marines and tossed in a pair of Storm Talons, which are the far more impressive flyers. These units aren't really the hardest hitting, wipe you all over the board by your face type units. Unlike the Hellturkey which is highly mobile, can inflict more than a few wounds that can wipe out swathes of MEQ's and is hard to hit and kill.
And if you haven't tried fighting the Knight in a game yet, it's really not as terrifying as you might think. I took it to a tournament recently and still lost every game. (It was blown up by one of the least cheesy Eldar lists I've seen in a while. Only army to do so that day.)
This is hardly a cheesy army in my opinion.
