5th Edition

It sees that, once again, Games Workshop has decided to revise the rules for Warhammer 40,000. Don't worry! It's a good thing. There are tons of new twists and turns to playing the game that will maker players sit up and take notice. I'll spare you the details of the actual changes, but if I refer to them later, I'll explain them. The real purpose of all this is to take a look at some popular unit configurations and change them around.
Space Marines
Assault Cannons are still good - they're just not as good as before.

This is more or less a fun list I put together to facilitate using three units of Ogryns. They're decent in close combat, except against powerfist-wielding units. They're great for charging into cover since they come with frag grenades, and they're great for taking on high-toughness models that have weak saves (like daemons!). The rest of the army is just a whole lot of vehicle-based shooting that can smash a hole through a lot of different lists.
