After banging through MT for a bit, now, I have a few bits to contribute/ask.
I am mod-ing Cbt Rifleman to include Rifleman. If you get Rifleman-3 and you also get Combat Rifleman-1, you would treat it as Rifleman-4 and a -1 in all the things covered under Cbt Rifleman, but not under Rifleman.
MT specifically says any weapon. I prefer the CT rule of a weapon in which you already have skill.
Is there errata for the alien books? I have found a few items in Aslan chargen that appears to be a problem. (Like Blade Combat in one of the skill lists, the mention of Adepts in one place, but nowhere else, etc.)
