After spending months trying to track down this report I’ve finally managed to get a copy through the CIA’s freedom of information act office.
First impressions
Also the vehicle examined still had the older 4-speed transmission and no radio onboard. I thought all T-34/85’s had these… The report is 453 pages long, so it will take me some time to scan it. In the meantime read WWII Myths - T-34 Best Tank of the war.
The report is called ‘ENGINEERING ANALYSIS OF THE RUSSIAN T34/85 TANK’ and contains analysis of all the components of a Soviet T-34/85 tank captured in Korea.
First impressions
The T-34/85 seems to have been improved in terms of performance and reliability compared to the T-34/76 examined by US experts at Aberdeen in WWII. However the transmission failed again.
