Grendel stuff is quite large and chunky. It was produced at the same time as the original Copplestoe Future Wars figures for Grenadier and I've often used them together (all sold now so no photos, sorry).
One thing to be wary of is that the loader claw from the cargo bay is a single sided piece with no back detailing and requires a certain amount of modelling skill to make it usable, skills I was sadly lacking when I originally bought it...
Overall though, a good range of scenery and worth getting.
