Some of the Naval Aviators were fast tracked into the war zones the first couple years of the wars in Afghanistan and Iraq.

I want to say I got the information from the Speed and Angels Documentary in 2008. I believe the one main character, Jay Consalvi, only had something like 200 hours when he was called upon to give some air support to a convoy that was ambushed by a well planned roadside bomb placement team.

As for helicopters. My buddies in the Army were deployed flying in the war zones with roughly 200-300 hours. Fresh out of Ft. Rucker to fire hellfires on targets. They were basically training in the Apache front seat as a Weapon's Officer. Learning on the fly.
