Working on a GSC army, going for a complete brood brothers theme (not just the IG units, everything). Basically I'm going to have a neophyte squad which are cadian shocktroops with swapped weapons and proxies for the other weapons. I'm struggling finding a proper alternative for the mining laser, I was thinking a modified lascannon, but I'm not sure where to get one that looks "portable" by a guardsman. Any anon have a good idea?
