if someone could post a pic of the urban camo set i'll tell you if thats what they are. Anyway, MISB $19 plus shipping virtually endless supply.
Urban Camo Ruination was released under the Robots in Disguise line. And was a mix of greys/whites. Universe Ruination has a more desert-freindly camo pattern. If its the Urban Camo version, I'd be all over it. EDIT: This is the Urban Camo version http://tfu.info/2003/Decepticon/Ruination/ruination.htm
