Has anyone gone from USMCR to NG and completed a Warrant Officer package?

To my understanding, you can actually submit a flight warrant packet right now, while your still in the USMCR. I would find a NG recruiting office and get more detailed information. Just some advice, if your goal is to fly, don't limit yourself to just Kentucky or to just the Army Guard, the Army Reserves, and other reserve branches have rotary pilots slots as well, also don't limit yourself just to the warrant option to fly, in certain cases commissioning to fly, can be a point of less resistance, to get your wings. And if your ultimate goal, is still to be a warrant aviator, you can always transition from commission to warrant.
