I recieved a nice e-mail from one of our readers , and I will quote it:
Dear thearmoredpatrol blog,
I would like to inform you that the missions, which you have mentioned, were released by our marketing team as part of a test campaign. It means that not every player is going to receive them.
Each player who gets such a mission, will be able to fight for additional prizes in-game.
Unfortunately, as mentioned before due to the fact that this campaign has been released only for test purposes, we can not give you more information on how to obtain such missions,
However, if it will receive positive feedback from our Tank Commanders, it might be put to the game and be accessible for every player.
Apologies, but in this case we cannot do anything in order to grant that mission for you.
Should you have other questions, do not hesitate to contact us again.”
