The last Militaria Hors-Serie No 95 is dedicated to the US 101st Airborne in Normandy. Among other nice information and colour plates it shows the camouflage of the Stug IV of the 17th PzGrDiv. that fought against the Screaming Eagles around Carentan. The 17th PzGrDiv. had 42 of these relatively rare Stugs, when comparing with the Stug III.
As far as the images on the article shows try to cover Dunken Gelb with the other two camouflage tones up to 80/90% in big blotches in which the Red Brown always touches the Green.
The models are all Revell exceptuating the one to the far right which is Altaya. They are organised in three companies with a command Stug with two crew visible which is my way of marking the CO in an AFV unit.
The Revell model is quite accurate but with little detail. The most important details missing are the tool box (behind the left side cuppola); the left side extra tank tracks....
