Concealment rating is the worst in the entire game.You may find yourself turning the tank often. Frontally, you'll only be hit with AP shells.
Although it uses the same hull as the FV215b, it lacks decent armor. As its name suggests, it holds a 183mm gun the largest gun caliber in the entire game. The FV215b 183 is a tier X British turreted tank destroyer. As of Update 8.6, the FV215b 183 received improved graphics that made the 183 very similar to its PC counterpart. It doesn't have great armor, and the tank has the second slowest reload time, only beaten by the KV-2. The FV215b 183 is arguably the 'most powerful' tank in World of Tanks Blitz (by damage, penetration, and gun caliber).
