Ross Kemp has struggled to control his anger since returning from a war zone.
The former 'EastEnders' actor - who recently made a documentary series about British soldiers in Afghanistan - admitted he has had trouble adjusting to normal life since.
He told Britain's Zoo magazine: "After my first trip, I came back and I got really angry.
"I was driving through London on my way home, and people were just on their way to work. And suddenly I felt furious. All I could think was that the guys out there were going to get shot at today, and these people didn't give a f**k. I felt they should - particularly after my sixth pint.
"My girlfriend actually had to take me home, because I'd got so angry that I wanted to start punching people. The pressure being out there - the knowledge that you could get blown up at any point - messes with your head
"You don't see people losing legs and bodies being put in bags without it having an effect on you."
He added stories of the things he's witnessed can have a profound effect on people and have caused some interesting situations at parties.
Ross added: "Coming out with me, you're never going to have a laugh. I start telling stories at parties, and I suddenly realise there are women in tears around the table. I'm like, 'Well, you did ask...' "
