Khodakovsky is a former head of the "Alpha" anti-terrorism unit of the security service in Donetsk, and one of the few major rebel commanders in Donetsk who actually hails from Ukraine rather than Russia.
There has been friction in the past between him and rebel leaders from outside the region, such as Igor Strelkov, the Muscovite who has declared himself commander of all rebel forces in Donetsk province.

Khodakovsky said his unit had never possessed BUKs, but they may have been used by rebels from other units.
"The fact is, this is a theater of military activity occupied by our, let's say, partners in the rebel movement, with which our cooperation is somewhat conditional," he said.
"What resources our partners have, we cannot be entirely certain. Was there (a BUK)? Wasn't there? If there was proof that there was, then there can be no question."
Khodakovsky said it was widely known that rebels had obtained BUKs from Ukrainian forces in the past, including three captured at a checkpoint in April and another captured near the airport in Donetsk. He said none of the BUKs captured from Ukrainian forces were operational.

While he said he could not be certain where the BUK system operating on rebel territory at the time of the air crash had come from, he said it may have come from Russia.
"I'm not going to say Russia gave these things or didn't give them. Russia could have offered this BUK under some entirely local initiative. I want a BUK, and if someone offered me one, I wouldn't turn it down. But I wouldn't use it against something that did not threaten me. I would use it only under circumstances when there was an air attack on my positions, to protect people's lives."
He added: "I am an interested party. I am a 'terrorist', a 'separatist', a volunteer ... In any event, I am required to promote the side I represent, even if I might think otherwise, say otherwise or have an alternative view. This causes real discomfort to my soul."
