Hey Yugo,
I did 4 Active and 16 Guard. Thinking back to BMT in 1985, I was there in July. Hot and humid at that time but May - June should be better for you. These are my recollections / ramblings.
Your's experience will likely differ. At the time we were fighting the Evil Empire - USSR and I was headed to SAC with a guaranteed AFSC to work BUFFs. Todays lower intensity conflicts may have caused a change in the training regimine.
The physical side of the AF basic was not as demanding as the mental side. I say that because PT starts out slow and picks-up the pace over time. It is a good idea to get in shape prior by running a couple miles a day. But don't get too caught-up in getting in steller shape. The AF doesn't kick you butt liek the Marines do. They have different roles.
For the mental side, always keep in mind that basic is temporary and never loose sight of the end-game - successfully graduating on-time. Remember, training is not the "real Air Force." Some guys lose it and literally throw themselves off the top of the mulit-story training buildings. They must have been close to the edge before they went in. Don't get too wigged-out by anything. Even if you have a rough time there, most of the BS paperwork about you will not follow you throughout your career.
You will have been successful if during your last mail-call prior to PCS, the TI calls your name and has no idea who you are. Don't volunteer for anything unless you smoke. If you take on laundry duty, you can smoke and BS with the boys while waiting for the clothes to get done.
I volunteered to be a Squad Leader. Not too bad a job but every screw-up my Flight of 13 guys had was a pain for me to resolve because the TI is yelling at the Dorm Chief, who is yelling at me and I gotta get my troop's problem resolved NOW. At one point the TI threatened to prevent me from getting Honor Grad due to my Flight's performance. It was in fact a threat but not enforcable.
Don't be a comedian, wise-ass, etc. You don't want to stand-out in any way other than quietly getting good scores all tests and meetign the PT requirements. Anonomity with the NCOs is a good thing. We had one guy who liked to pop-off now and then, yes it was funny, but he got the Squadron into trouble. To rectify the situation, one night while we Squad Leaders and the Dorm Chief were all fast asleep, the troops threw a blanket party on this guy. The next day he complained about it, and of course all of us in "leadership" positions had slept peacefully throughout the night and didn't hear a thing (he didn't get as roughed-up as Pvt. Pile in Full Metal Jacket did, but it was close). It did straighten his ass out and we stopped doing pushups for the knucklehead. He also graduated on-time.
I gotta go, but finally let me pass on to you the best advice I have ever heard concerining Boot Camp. When you are getting your ass chewed up one side and down the other, you can feel the heat and spit from the TI in your face, your hot and pissed and thinking of doing something stupid - like take a swing (which the TI would love for you to do 'cause if you do, it shows you are weak. If you can't take the verbal abuse in your face, how the heck are you going to be there when the SHTF and you bud's need you to do your job.) Remember this phrase, "it's not the way the TI is saying it, it is what the TI is saying that matters..." If you get caught-up in the WAY things are being said, you will get pissed and miss the point. WHen you first get to BMT, the TI will yell at you 'cause you're there. After two weeks, he's generally yelling because someone has screwed-up and deserves to be straightened-out. DON'T GET CAUGHT-UP IN THE WAY THE MESSAGE IS CONVEYED - LISTEN TO THE MESSAGE AND CORRECT YOUR BEHAVIOR. That worked really well for me 20+ yrs ago and will hopefully help you too.
Gotta help give my son a bath now. Good luck and thanks for defending the Greatest Country on God's green earth. We have our warts, but the US knows the difference between good an evil and acts accordingly.
Regards,
John (USAF Ret.)
