Based on the video evidence, I believe that the shells in video are 100mm shells that are typically used in the 1950’s Soviet era T-54/55 tank or Chinese Type 59. These shells have been obsolete since the 1970s, so it is highly doubtful that either Russia or Ukraine would be using these systems today.I believe that the shells in this video are new manufacture and headed to foreign state for their armed forces such as Pakistan, Iran or African states.
