The road wheel of the K21 Infantry Fighting Vehicle (IFV) is an essential component located on the lower part of the vehicle that supports and guides the tracks. It ensures stable and smooth movement by absorbing shocks and maintaining proper track alignment. The K21, designed as South Korea’s next-generation IFV, benefits from a durable road wheel system that allows it to traverse various terrains while maintaining high mobility and stability. This robust system enables the K21 to perform effectively even in harsh and uneven environments.
