Did the US Army use Sherman Fireflies during the Second World War?

Unresolved here. The tentative answer favours American 76 mm Shermans and tank destroyers as the equivalents, while audience comments challenge the recollection.

Clarke's tentative recollection is that American units relied on 76 mm Shermans and tank destroyers as their alternatives to the British Firefly conversion. Audience comments challenge that recollection and distinguish the Sherman gun and suspension programmes. He remains unsure about American Firefly use and says the point needs further research. The M10 emerges as the tank destroyer he had in mind, but the exchange leaves the original service-history question unresolved.
