you might find this interesting - temporary premium tanks mechanism arrived on Russian server. The event goes as follows:
From 10.3.2015 to 13.3.2015, using KV-85/KV-2/KV-3/IS/SU-152/ISU-152 or ISU-2, destroy 2 enemy tanks and damage three more. Repeat this 25 times and you will receive temporary SU-122-44 to use for 4 days (after which it will get removed).
What you think?
