Collecting a large variety of imperial guard is somehow very rewarding. The different guard regiments are distinctive in their look and their fluff is interesting. It’s just a shame that the official range of imperial guard are some of the smallest minis in size [Ed: though Slick Devlan is probably the smallest of the lot].
The official range of imperial guard is limited, but there are many 3rd party options.
I still have a few more guard to paint up. Even some Vostroyans i want to convert from those plastic Tehnolog polar soldiers.
