There nice conversions, but I'm a bit confused as to the weapon options.
The configs you've modelled are illegal under the rules. Is this deliberate? For example how can a terminator use a storm bolter and an Assault Cannon, and how on earth is it possible for him to hold the Assault cannon in a Power fist?
Also whats the small little bolter doing on the powerfists of the other marines. Very Marneus Calgar, but once agian totally useless in a game I'm afraid.
Are these just funky conversions for your cabinet?
