I am a big fan of the Hetzer. I mean, it just looks cool to me. Sure it is only a short 75mm gun and lightish armor (on par with the PzKpfw-III)...but it is well sloped and a sleek looking machine.
The Puma is my all-time favorite armored car. 50mm gun and a lot of mobility! And bad-ass looking too!
As for the motorcycle, I thought it would make a nice little recon team...you know, just the type of unit that can sometimes be a pain in the butt but not a real threat. Could also be used as a "messenger" type of unit.
Fun stuff...more to come.
