Middle East War(Iran)

We had planed to construct over 120 units of several kinds of tanks for IJPC project in Iran.
However, the construction was interrupted before completion by Iran Revolution in 1979.
The story that all employees who engaged in this project escaped with bare life to Japan by various assistance has been handed down.
