Yeah, starting with some of the smallest infantry models available may not have been the best call on my part. But hey, grimdark universe means plenty of opportunities for “battle damage”

So a thing that hugely helps here is to go get yourself a wood dowel and cut it into little 3 inch paint handles. You can stick the model on with museum putty or put a magnet on the bottom and use a metal strike plate like here to stick it in with a magnet
