that many death korps is gonna cost a pretty penny though...
I quite like the hades breaching drill- 50 pts for what is essentially a drop pod which gives a S10 AP1 5" blast where it surfaces, 3" blast meltagun on the front, and has S10 rams, which is not only able to transport what is essentially a 5-10 man veteran squad with 4+ saves and shotguns, but also any engineer squads after that can surface through the hole it made. Those engineers with a demo-charge can cause merry hell for quite a few units.
You can also accompany an engineer squad with a commissar-general, which would boost it's close combat effectiveness no end.
Also the cyclops demolition vehicle is quite useful too- a remote-controlled demo-charge for 25pts? Yes please ^^
From what I hear, the punisher looks good on paper, but the (I forget the name) one with the no-cover saves cannon is more useful and suits death korps seige warfare style.
