Military medical training efficiency has leapt. The US military's combat injury rescue simulator uses a modular
sex doll head that can instantly switch between blast injury and gunshot injury modes. Its airway management system can simulate blood clot blockage, requiring trainees to establish an emergency breathing channel within 90 seconds. Actual combat data shows that the battlefield survival rate of medical soldiers trained with this device has increased by 22%. However, it is difficult for the standard
torso sex doll to simulate the pupil asymmetry signs unique to craniocerebral injuries.
