I have put my Ork Kommandos on their bases.
I have decided to paint their backpacks separately, so will need to mount them somehow.
The boss (Nob) has a separate arm and head, so I stuck them on.
One of the nice touches (Jes Godwin told me this) is the bullet hole in his left boot just below his Slugga holster.
It’s as though one day, he was holstering his pistol and BANG!
