Final layout of the "Range finders" scene can be seen on the pictures below. I made some research and found the perfect time period for this scene when 2. Falschirmjhager Division was operating together with 11. Panzer Division in the Kirovograd area in late 1943/early 1944. So we have a FJ trooper discussing things with the recon troop of the armored unit their cooperating with along with the tank crew in the background.
