There isn't any detail on these. It's purely to keep them from falling over during the game. What would have been neat is if they had sculpted some grating under them, as if the Terminators are cautiously moving through the corridors of a ... y'know, Space Hulk.

I did that for my Vindicare Assassin and a Devastator Squad I was working on so they could match the top of the Imperial Bastion I have on my display board.
