A wolf pack of at least 30 thugs viciously attacked two hero ex-Marines in Brooklyn after they rescued a teenage girl who was being assaulted, police and witnesses said yesterday.

And when the brother of one of the former servicemen tried to come to his rescue during the July 25 melee in Coney Island, he was beaten into a coma.

The former leathernecks, Valentyn Olenyev, 23, and Boris Bukler, 22, Russian émigrés who served tours in Iraq, were walking a female friend to her parked car on West 23rd Street at 12:30 a.m. when they spotted two men holding the screaming teen by her hands and legs.

'She was yelling, 'Help!' ' said Olenyev. 'I asked her, 'Do you need help?' She said, 'Yes!'

'It wasn't our intention to get into a fight,' said Bukler. 'We said, 'Let the girl go, and we'll leave.' We told them, 'Stop.'

'She was screaming, and all we did was look to help her. I got a bottle smashed over my head, and after that, I started fighting. But I got beat down.

'I was getting my ass kicked by 50 people.'

....Ivan suffered multiple facial fractures and will require plastic surgery.

The two former Marines, meanwhile, insist that the violence had racial overtones, although the assault has not been labeled a bias crime.

Bukler said, 'Those in the crowd were yelling, 'Hey, white boys, you're in the 'hood now!' We were yelling back, 'We don't care - we live here!'
