Note: This challenge is now finished and can no longer be completed.
Same as the other challenge, If you already played 10 games on the 360 this will unlock upon starting the game and accepting a few things. (keep pressing A) If you're new to World of tanks simply go into multiplayer, and play 10 matches. Fastest way to die is to rush to the enemy base, and let them kill you. Then Exit the game you're in and restart a new mach with a different tank. Shouldn't take very long to get this one.
