Probably not yet. Even if there was a VR headset and suit setup that made you feel pain and felt/heard explosions at dangerous levels, it would not be the same. You won't have the genuine fear of death and won't experience the same level of psychological trauma. Maybe some day there will be a brain interface that allows you to re-live or experience combat real time. I hope Elon does not read this. I could see a not too distant future VR setup that makes you better at shooting moving targets and controlling drones that assist you. Some games already make an attempt at this.
