If you want to experience military flying, I’d say go for it. Regardless of airframe and mission, military flying is way more challenging, fun, and fulfilling than any airline flying by a large margin. Having said this, why not try for a fighter unit? I don’t mean to turn this into a fighter vs. heavy thread but if you’re shooting for maximum fun factor, there’s nothing like the tactical jet world. I have many friends who chose to fly heavies and enjoyed the mission but I would never trade my experience flying a pointy nose jet and pulling more Gs than a human body can handle. I wish I had known about the ANG in high school before I chose the academy route. Guard/reserves path is more enjoyable than the active route, in my opinion.
