You will provide them with your personal information, your educational history, and health history. You must also supply your DAT scores and transcripts. You will then go see a military doctor who will examine you for obvious health problems and to review your health history. You must apply through your Officer/Medical recruiter. He/she will get you the application. I understand the acceptance rate to be more difficult now than about 8 years ago. When we were invading Iraq, no one would join. Then they started offering sign-on ($20K) bonuses. Now that if feels like things are dying down in Iraq and Afghanistan, many want to join. Additionally, the economy has taken a nose dive so job opportunities are not as prevalent upon graduation. The military is a no brainer. The HPSP scholarship generally offers 2-year, 3-year, and 4-year scholarships. I have hear of 2.5 and 3.5 year scholarships too. The AF, as I understand, rarely offers 4 year scholarships or sign-on bonuses. You need to speak with the recruiter. AF recruiters are notoriously difficult to reach, won't return emails or phone calls. If you really want to speak to one, you better find out where the office is and keep knocking. The AF, in my opinion, is highly over-rated. There is a perception that you will get paid better or get better housing. This is not true. Planes need a lot of space to do their training. You will likely end up in South Dakota or the deserts of Nevada. The Navy will send you to a shore somewhere. There are very few duty locations that aren't near a beach. The Navy also offers four year scholarships. If you're not going to get a four-year scholarship, I'd turn it down. You get a monthly stipend of around $2000 plus books and tuition. Not getting the 4-year stipend is like turning your back on $24,000 and a year of tuition with interest, and a $20K bonus. Army is OK too. You'll probably end up in Texas. Lastly the Army and AF require you to run 3 mi. every 6 months, but the Navy is 1.5 mi. Believe me, this is nice.
