Tigerman you're right,
However if they hadn't been like that, we wouldn't have had some of the most interesting war machines ever made to model now.
We wouldn't have things like the sd kfz 250 - funky even for a half track
All those 8-rad & vehicles with two way driving
Some cool planes like the ME 262 & the ME 163 Comet
It's good for modelers 50+ years later
