I usually don't build a tank that has figures, but I do have a few projects that turned out ok with 1/18 figures and a couple with 1/16 figures. I have a big bunch of infantry types, but they are not tank crew types.
My Hellcat crew.
My Greyhound "keep your head down" guy.
My only British Bloke in a Bren.
My Sd.Kfz
And finally --- a tanker with an attitude --- don't they all have one?
It's one of my silly soldier things I did as a joke cartoon character series.
Don't take it personally !!!!

P.S. All of these are r/c, not just static like my recent projects.
