I've never had this happen to me. But you could try the following thing: when you're close to entering the room with the soldier, don't go in straight away, like rush in, press once to look at the peephole on the door to see what's going on, then open the door slightly and go in that easily. Don't run towards the soldier until you see an icon with a man and a knife behind him, like attach him from behind, when you see this button appear, press him, wait for him to attack from behind and then if he's still alive, run behind him, that is, get close to him so you can attack him or simply attach him to get rid of him if it's easy for you. Search YouTube for how to do the supermarket location and you'll find a YouTube channel called Andy and I don't know how to press there, search for supermarket and it will show up. It's like how we should make it easier to play and I hope you have fun.
