Given his service history, I'd see Iosif fitting well into the role of the pilot or acting as added support in a (stolen?) gunship raining hell down upon anyone unfortunate enough to make the mistake of screwing with the team, or even acting as a distraction whilst the main crew infiltrate a secured setup. That said, he's not exactly a pushover - he'd be more than capable of fighting alongside the others when the pyjak dung hits the fan.
