IMDB網站記載的完整片長是167 min, 若扣除開場/中場/離場音樂片段, 大約是163 min.
台灣發行的公版片是156 min, 跟美版VHS/LD是一模一樣的, 據說有若干片段已經遺失了, 然而丹麥電視台曾經播出過較長的版本, 但還是不完整.

Alternate Versions for Battle of the Bulge (1965)

The US and UK video versions are somewhat shorter than they ought to be (a similiar copy was shown on Danish TV some time ago). True the copies are longer now than when it first came out on video in the early/late 80's, but there are still sequences missing. That's the reason why the quoted running time on various reference works differs from how long available versions actually is. In short:
When Robert Shaw visits the German hedquarters there should be a sequence just before Werner Peters switches on the lights in the operating center where Shaw and Peters had been ambushed by what appeared to be US parastroopers in the corridors. They turned out to be Ty Hardin's German bogus US paratroopers.
After the town held by Charles Bronson is overtaken by the Germans there should be a confrontation/interrogation sequence between Shaw and Bronson.
Shortly thereafter Shaw gets attacked by a young boy outside the Town Hall. The boy is about to get shot, but his father pleads for his life. The boy is freed and the father gets executed instead.

Also the Danish video copies contains one further sequence in wich Shaw inspects his tanks.

There's also one more scene where Bronson and Fonda discuss Fonda's presence in the war over a cup of coffee.

The 163-minute cuts out the Overture, Intermission and Exit Music. It also removed most of the sequence involve the artillery train. The 163-minute version also is pan-and-scanned signifigantly differently than the other pan-and-scan versions of the movie.
