having gotten bitched out of Marine Air by my Company Officer I can tell you this: they are good people, real chill (for being MArines), who work hard and do more with less. You have a better shot at jets, and if you get them you will do more A/G Support missions. And they NEED pilots right now. For my class ('09), they were begging the MArine Selects to go pilot (which pisses me off b/c that was my 1st choice). I would not go Marine FO. If Fo is 1st choice, then go Navy.
About the Growler: the Marines don't want it/ can't afford it. They are gonna milk those prowlers for all they are worth b/c its the cheapest solution. EA6B's'll probably be here until UCAVs replace us all bud.
