Jagdpanzer IV pics:
Disc pattern
Soft edge
Solid Dunkelgelb also seems to have been quite common
The "ambush pattern" per se was not applied to Jagdpanzers. They used the factory-applied "disc pattern" and not the over-modeled ambush dots.
While we're on the topic, I'll post a picture of the vehicle I'm modeling:
It's definitely an A-0 (aluminum armored training vehicle) and has Schulungsfahrzeug on the side (the name of the Jagdpanzer training school)...but it has zimmerit too, which wasn't supposed to be applied to these vehicles. Many of them were pressed into service towards the end of the war, and were upgraded in various ways before facing actual combat. Do I smell field-applied zimm?
