Comparing: Aufklärungspanzer Panther vs. T71

Planned heavy reconnaissance vehicle. The plans called for using the Panther hull in order to facilitate rapid mass production. The vehicle was to feature the Leopard turret with a gun not longer than the tank's hull, which was to ensure maneuverability in forested terrain. No prototypes were built.

Experimental airborne light tank with an oscillating turret and automatic loading. Developed by Detroit Arsenal from 1952 through 1953 as a replacement for M41. The armament was deemed ineffective, and the development was stopped after one wooden prototype had been built.
