Grey Knight Terminators are a must for almost any SM army. I only have three in this army and are headed up by a Grand Master. Instead of going with the tradititonal colour schemes, I chose to paint them up the same colours as the rest of the models. I felt this could be used to represent that they are a permenant addition to the army. Also I made sure that one of them was equipped with a psycannon for a little extra juice. The bases a custom made out scrap pieces from my bitz box and some plasticard. I want to get some more for my current RS army project just think they would look sweet in a mech warrior paint scheme.
