i can tell you from experience that virtual and real are very diffrent i did training in virtual reality with m4;s that had air power to simulaite a bolt firing. and that is totally difffrent then real life. i have not met anybody who hasnt had combat ptsd so i cant say but frrom what i read that the symtoms are similiar but diffrent. it all depends on the situation. but it seems like people are getting more and more mentaly weak. they cant handle alot of mental punishment. and i think that is why alot of people are getting ptsd from stupid fake stuff like playing a video game. its fake you are not going to get shot you are not going to see dead people you arent goinig to see your best friends get shot and loose limbs. and if somebody is getting ptsd from playing a game im glad they arent in the war because they couldnt handle it. and if i was at war and couldnt count on the guy next to me to save my life then i would be real worried.
