The 75mm HV had been intended to rectify this, but prior to entering service it was found to be too large to fit in the Cromwell turret. Instead Cromwells fought alongside the 17pdr armed Sherman Firefly or Challenger, both of which could destroy Panthers and Tigers at standard combat distances. Cromwells (and 75mm armed Shermans) were supplemented by these vehicles at varying ratios per troop of 1/2 to 1/3. Though this provided a good solution to the issue of heavy German tanks, it added an additional level of complexity for battlefield commanders in having to place the 17pdr armed vehicles tactically within a formation. However this complication was not unique to the British army, the US employed similar methods and faced the same issue with their arsenal of 75mm armed Sherman tanks.
