I tend to agree. Actually Battle of the Bulge made a serious effort to get the sense of the equipment . They showed the difference between the TigerII and the Sherman by using M47s as Tigers and M24 Chafees as Shermans. It gave a good idea of the difference . The camouflage paint on the Chafees was ridiculous. OD 33 was the normal paint job for US vehicles. One fact I remember in the flick is a scene where some German pridiners have been taken and Fknda is examining their weapons and a very modern looking rifle is examined. I was in HS and had no idea what it was. Turns out it was a Stug44. That weapon armed many in the Volksgrenadier divisions.
BOB has a lot of stars, including Henry Fonda, Telly Savalas, Robert Shaw, even Charles Bronson. It’s an inaccurate film but a lot of fun to watch. After reading a very well researched book on WWII, I realized the general story of the film is kinda sorta correct. Having first watched it as a kid, I remember just about all of its scenes.
