Army is right, as a former Marine helo pilot, I can attest to his post. Those guys fly their asses off compared to a Marine Officer. As a Marine Officer, your responsibilities are many and flying usually comes in last. As for me, checking into my first squadron, I had 13 squadron jobs, and pilot was at the bottom. Not in war time, mind you, but 200 flt. hours a year was a big year.
Now, that being said. When I was flying, my missions were second to none. Some of the best flying out there is in the Marines. Period.
I'm now flying for a Major Airline and travel across the globe, making a good wage, but often my mind drifts back to the smell of the 50 Cals, and the **** and vinigar of a Marine's voice as he yells "go", "go", "go!" while the young Marines charge from the Helo.
Remember though, the Marines life is a hard one. You will often be without comfort, aid, or cash. But you will always have strength, esprit de corps, and pride.
Good luck with your decision,
Aloha
