Meet The Mighty: EP5, M4 Sherman
April 4 2017
No, you didn't mishear me. Mexico still uses military vehicles based off the M4 chassis, and it's still the main battle tank of several nations. Each M4 only cost $30,000 or roughly $500,000 in today's dollars. Sorry about that microphone distortion in some sections, didn't realize it until after the video was done.
