K22 IFV is the Royal Joseon Armed Forces's next-generation infantry fighting vehicle. It was developed to replace part of the K200 and complement the K21.

K22 was developed by improving the AS-21 Redback IFV to meet the needs of the Royal Joseon Armed Forces.

Design

K22 replaced the existing K-21's aluminum composite armor with steel armor, and fitted additional armor to meet the needs of the Royal Joseon Armed Forces. After all these improvements, the K22 had a stronger defense than the K21, but it weighed significantly more than the K21. Because of this, the K22 had to be equipped with a more powerful engine than the K21. The K22 addressed this issue by installing a K9 self-propelled howitzer's power pack engine, which had more power than the K21's engine.
