Space Marines
(In General)

Imperial Against Marines:

For the Imperial Guard Commander, I have thought up of several ways to combat the "uber" Space Marines.

First, establish a foothold in some good cover and put a lot of far reaching firepower into there. All your lascannons, autocannons, etc will go there, probably with your HQ or Infantry Plattoon Command Sections... Now, once you lower those numbers of SMs running around, drop ship in some Storm Troopers with Melta Bombs, or use Veterans (You could also infiltrate) and eradicate everything... Also, it doesn't hurt to drop in some meat shields to protect your important troops (IE: Regular Guardsmen), and they might even kill some stuff too...

OR, instead of all that, JUST USE GREY KNIGHTS! Drop ship them in right next to enemy deployment zone and pretty much all you do is slaughter them... :D
