Military anti-shock trousers

Military anti-shock trousers are like giant pants that help soldiers who might have hurt their blood system. When a soldier gets hurt really badly, their blood might not go to their important organs like their brain or their heart. The anti-shock trousers help by squeezing the legs really tight, kind of like a big hug. This makes the blood go up to the important organs and helps the soldier stay alive until they can get proper medical help. It's kind of like having a superhero helping you out!
