Thanks for the kind words guys, I get too easily distracted to finish anything off completely recently, so these will probably stay at tabletop standard, maybe if I get a few hours sometime I'll finish them off.
Most of the conversion bits came from my bits box which is heavily populated with GW plastics purely because they're easy to convert, I think the missile launcher was from the drop pod. The .50 cal was made from brass tubes and a bit of putty in the middle with holes drilled in for a heat shield thingy. (technical I know)
