Dai asked how they size up next to the Chimera. Mine wear an IG auto cannon, smoke dischargers and a searchlight because I've got them as counts as salamanders. I suppose they could stand in for Chimerae. If you're not playing 'friendly' games I could see someone complaining as they are a different shape and therefore must surely be easier to hide and therefore you are cheating, but I suspect such an opponent may well outright refuse to play someone who isn't using 100% GW. (what is all this about FW suddenly being 'allowed' ? They have always been made for the game and accompanied by 40K rules ffs.)
Another shot to compare with a Chimera. Slimmer, longer, but more or less the same height, Including the (obviously unmanned) turret.
Showing the Green and Green scheme off. I will eventually put another green on (there is a third green on there, but I think it's the same as the base colour and therefore more or less a shading colour so subtle only polinating insects will be able to see it).
