Games Workshop have posted a series of 40K Space marine army lists focused on one of the several characters from the latest Marine Codex.
From their website:
For the gamer amongst us, one of the things that make these characters most interesting is the effect that they have upon our armies – many of them enable us to select different units for our armies or to alter the tactical disposition of our forces entirely. In this article we’ll take a look at five of these heroes, and the forces that they command. We’ll present a sample army list for each, and a little tactical advice on how best to use it in your games. Perhaps these ideas will inspire your own Space Marine forces – after all, if you can exploit the potential of these mighty heroes to their fullest, victory will surely be yours.
