Army Pilot" did an exceptional job at explaining things. I might add that you really should buckle down on your grades this next year and try to get straight A's (it is entirely possible and up to you to do that). If you do well it will improve your chances.
Now from your information: being nearsighted will definitely limit if not eliminate your chances of flying, particularly for the Air Force. It will depend upon just how "nearsighted" you are and whether the military is short of flyers or if they have too many applicants. I would hazard to say that anything less than perfect vision will completely eliminate your chances of flying fighters at all.
But as I stated in the first question, in the Air Force you definitely want to go to the Academy if you want to fly fighters. My recommendation for fighters at this point is to check out the Navy or Marines, but there are no guarantees. You are likely going to have to sign some kind of contract which will mean 3-8 years of service even if you don't fly what you want.
The highest chance of actually flying is in the Army. I suggest going Warrant Officer. You will get more flight time and will fly longer.
If you go OCS/ROTC and become an officer you will not fly nearly as much and that will quickly diminish as you get promoted to Major and Lieutenant Colonel with it almost disappearing by the time you might make Colonel. As a Warrant you will probably be able to fly all the way through your career. Army aviation as a Warrant does not require any college, but it could be helpful to have a couple of years before going that route.
However if you want to get started sooner then go the Warrant route. Warrants are officers without so much of the hassles. Your CAP experience will be helpful.
Now should you insist on fixed wing aircraft they the Air Force or Navy/Marines is the route to go. If you are flying transports you will probably spend more time flying but again as you gain more rank (Major/Lieutenant Colonel of Lieutenant Commander/Commander) you will start to loose time flying as you do command positions and other staff time. The services other than the Army really don't have Warrants flying and so that isn't much of an option.
In the Army they have CH-47 Chinooks (Twin rotor heavy Helos), UH-60 Blackhawks (Medium utility), OH-58 Kiowa (observation/utility/gunship), OH-6 Cayuse (Observation, gunship) commonly called "Little Birds" AH-64 Apache (Attack). The common Air Force planes (not fighters) that you might see are C-17s, C-130's. The C-5's are older and begin fazed out.
Then you have the B-1, B-52 Bombers. The A-10 Warthogs are the most loved aircraft by the Army as they are awesome in putting lots of firepower and destruction on the enemy. I am not as familiar with many of the Naval/Marine aircraft other than the C-130s they have so I'll have to defer there.
I would suggest that if there are any in your area, to look up the Air Guard, Army Guard (aviation units), Naval or Marine Reserves (aviation) and have a talk with them. You can do this without making any commitments or contracts. Just ask them all of your questions, listen to what they say and then go ask someone else to try and get a balanced response.
If there are none in your area, try calling some (you can often find them in the phone book or online). Good luck.
Being blunt - being nearsighted you cannot be a pilot in any of the services. You can, however, be a Naval Flight Officer in the Navy or Marines and see direct combat. If I was in Naval Aviation right now I would be flying in the back seat of the EA-18 "Growler": http://en.wikipedia.org/wiki/EA-18_Growl... Want "shoot it down the throat" combat?
Check out the "Wild Weasel" mission reserved for the EA-18 and the EWO (he conducts the entire mission): http://en.wikipedia.org/wiki/Wild_Weasel.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
