Get the Grom With a Raucous Discount—or for Free!
The Rolling Thunder event runs for 11 full days and consists of 10 Stages. Each Stage can be conquered either by mastery or by commitment: just complete the corresponding mission! Every Stage you reach adds 10% to your discount on the Grom bundle and gives you additional rewards. Finish the Progression and get this thunder on tracks for free!
Missions for Commitment
These missions may take longer, but they are generally easier to complete. Remember: These missions must be completed in Tier VI–X vehicles, and mission results will only count if you finish in the top 10 on your team by XP earned at the end of the battle, regardless of whether your team wins or loses.
Missions for Mastery
These missions are trickier and more complex, but will save you time if you have the skills for them. These missions must be completed in Tier IX–X vehicles.
By the Name of Thunder
Grom is Polish for “thunder”, and this chariot of war fully deserves the name. Its damage at distances of 50 m or closer is a deafening 800 HP. It benefits from close combat even more than its relatives from the Polish Tech Tree! The SDP wz 66 Grom also possesses decent mobility and sloped frontal armor, making it perfect for hit-and-run tactics.
