Basically it's 2 vanilla sergeants, 9 regular guardsmen, a meltagunner and a new marbo (old one has been demoted to back to a veteran).
Managed to make this using one box of guardsmen and bits including the spare crew from my vendettas.
Went pretty overboard with marbo, but I think he looks cool and is definitely wysiwyg unlike the old one (who has no knife and has a shotgun on his back).
Haven't had time to post reports but look forward to games 2 and 3 from yesterday soon.
