“Today the Strv/m42 is going to the supertest as a Tier V Swedish Medium tank. We are exploring different possible roles for this vehicle. For today’s test we will check it as a tank with good dynamics and excellent elevation angles, but weak armor. We will also be testing possible top configuration for the vehicle. Game role will be defined by the results of several tests.”
