A casualty who is suffering from a sever cold injury should be rewarmed slowly?

Yes, a casualty suffering from a severe cold injury should be rewarmed slowly to prevent complications such as rewarming shock or further tissue damage. Gradual rewarming helps restore normal blood flow without overwhelming the cardiovascular system. Using warm, dry blankets and warm (not hot) water immersion can aid in this process, while avoiding direct heat sources that could cause burns. Monitoring the casualty's condition throughout rewarming is essential for their safety.
