It's hard to tell too much from just your one post, so bear with me. I may be way off base. That said..............

Joining any military service as an officer and pilot usually isn't an after thought when you figure out the civilian market isn't what you expected. It's also not a decision that's generally influenced by the apparent "stability" and potential "fun".

You're considering a pretty big step and it will require a sincere desire to serve and lots of sacrifice (potentially everything if necessary). I didn't really get that side of it from your post.

The military is stable as long as they need you. Compared to the airlines it's rock solid. However, there's plenty of guys out there who hit their timing wrong and were forced out during a down-sizing.

Just make sure you're doing this for the right reasons. Good Luck.
