Fully agree, there, Terry!
I truly enjoyed the movie "Battle of the Bulge" when I was younger, but it really irritated me that the Germans were using M60 tanks...I even recognized those when I was a kid ("wow..those German tanks look like the ones we're using in Vietnam!)
I never did see a M-60 in Vietnam when I was there, either time. I did see a lot of M-48s though.
A M-60 is just a upgraded M-48, more or less.
Those tanks in Battle of the Bulge were probably M-48s anyway. M-48s were the throwaway tank in the late 60's early 70's, they were using them as targets on the arty. range at Wildflecken, Germany when I got out in 73.
