World War One camouflage was often very bright colors.
This A7V I think is from It Figures. It's a big block of resin.
The Germans made use of a lot of captured tanks.
This is a British Whippet tank, captured, repainted and put into German service.
The British made 200 of them and they could go 8 miles per hour.
If you don't think that's fast try and run eight miles per hour.
Germans were very careful to repaint the captured tanks so they did not get attacked by their own men.
