Congrats Calex!
It will be very interesting. I had an unbelievable time in the Navy, got trained as an aircraft electrician and got money for college (which i never used ). It was totally worth it. Take every single program they offer you and if at all prossible push for a West coast deployment when you graduate "A" school (which did you choose BTW?). I say West coast because it is by far the better coast to be on for deployments. I was stationed on a carrier (CVN-65, CVN-72) and we got to do port stop all over the Pacific and South America.
The biggest obstacle to being in the military is the "BS". Your ability to adapt to that is the single biggest factor for your happiness or misery. You have to be able to roll with the punches. A lesser factor is the isolation from your friends/family while deployed at sea for 6 months. Luckily for me, I joined at 18 so I didnt have a wife/kids/bills to worry about but I saw it destroy many a person.
Regarding the war. War doesnt really exist for those in the Navy. During Gulf War I we just floated around launching bombers and fighters. There isnt anything to threaten our Navy out there so dont even sweat that part. Plus you will get: 1) Tax free pay, 2) Hazardous duty pay, 3) Free postage!
