Depends on;
what YOU want from your career?
equally
what YOU want to give during your career?
[For reference I am making vague comparisons to civvy flying, airlines]
If you want to get into the cockpit ASAP, forget it. It will take you +6 yrs to get front line with around 2yrs holding.
You have to spend a year beasting at IOT.
Altho pay is good, by the time you are mid career (30's-40's), others in the airlines for example will be earning double yours.
You have to fight, war etc...
You are an Officer first, not a Pilot.
Unstable family life; having to move bases every tour (3yrs)
