This one was trialled by Canada. I think its got a 75mm gun, timeframe is 1980:
Oh wow never seen this Piranha 8x8/AAI 75mm M32 gun turret combination before 😮😋
How the 82nd Airborne could have/should of had this in its ORBAT as an M551 replacement!
I wonder if it retained its amphibious capability with that gun/turret configuration (I can see propellers and trim vain, but not sure about retention of balance 😜)
Also wondering if it would have retained that amazing +22 elevation that was seen with the AAI Rapid Deployment Force/Light Tank ['AAI promoted the M32 as a dual-purpose gun in that, when elevated, the system could be used to counter low-flying aircraft as in a self-propelled Anti-Aircraft (AA) system']
