In October 1954, 66 years ago, T92 Light Tank appeared for the first time. While originally designed as an airdrop-capable replacement for the M41 Walker Bulldog, it was never accepted into service. M551 Sheridan was adopted instead, mostly for its swimming capabilities. http://pbs.twimg.com/media/Ej0m2G2XcAIzAH5.jpg
The Jagdpanzer IV appeared for the first time 79 years ago. The Jagdpanzer, meaning "hunting tank" in English, fought in Normandy, the Battle of the Bulge, and on the Eastern Front. The IV version was coated in Zimmerit to help protect against magnetic mines. http://pbs.twimg.com/media/Fej775zXkAAIpAb.jpg
