What a great thread!
My 2cents;
Things I wished I would have done prior, (I joined up right away, late in life, because
I was getting old [27] and I thought we were on the war-path, this was the early 80s)
But you have a lot of time.
I admire you going infantry, 11B all the way, every day!
Many folks are scared of going infantry, because it isn't a good post-military "career path"
I say, don't discount the military as a career path. Infantry is what it really is all about.
As everyone else has said, physical conditioning. First and foremost. Run, alot.
The run some more.
Nothing in the civilian world is going to make you fully competent with a light machine gun,
like the M249 (which we didn't have) so don't bother. My marksmanship skills atrophied during training, we didn't get to shoot NEARLY enough, but that was then. Modern times it seems you have more access to combat veterans, so all of this may be different.
The run some more.
Check out the specs of weight for a full combat load in different theatres, you can look most
of this stuff up for the regular leg infantry. Build up a curling bar weight set to mimic the M249,
and some kind of rucksack and bags of sand to mimic a combat load, and run with it, then run with it a lot more, then run with it some more.
Get some proper military issue boots that fit, and wear them, a lot, get your feet used to them.
Do this on your own time, no one likes a wannabe, don't be a wannabe.
Eschew civilian sunglasses and such.
If you play organised sports in school, learn to scream, A lot, scream all every chance you get on the playing field. This will help keep you from loosing your voice after a week of basic. If you don't play team sports, start playing team sports, and train, train hard.
Study armor, get as familiar as you can with all armor and battlefield weapons systems. Build models if you have the time, had a fellow in my squad at my first duty station who was a nerd,
kinda useless who knew EVERYTHING about any piece of equipment likely to be encountered
on the contemporary battlefield. He built models and studied them. Knew what kind of terrain
could support what kind of stuff, and what the supply requirements and threat levels were for nearly everything. Damn handy knowlege.
Pushups, sit ups, running, more running. Drink lots of water every chance you get. Stop with soda and coffee, and anything other than water. push yourself hard.
learn as much general knowlege, (David McCauleys "How Things Work, V1,V11, the New How Things Work) as you can. If your math sucks, square it away. Learn to print fully legibly,
If you have any bigotry, or prejudical attitude towards others, square it away. EVERYONE
to some degree or another is a bigot, learn to sit on it. Practice being humble, work on it until
it becomes second nature. Study being level headed.
When you start training, you are going to be tossed into a big vat with every kind of person
"they" can find. Then they will dog you. Learn to choke down getting angry, learn to suck it up.
Work hard at being a friend to everyone. This is really important, the more prickish your comrades are, the harder you need to try to accept them. You depend on these pricks to
watch your back and to drag you out of harms way, and they depend on you for their lives,
their mothers, fathers, sisters, brothers, wives, husbands, children are all relying on you to bring them home. It's a heady responsibility. If you like them, it makes it easier to shoulder.
On the one hand, don't be a show off, if you know stuff they don't, (because you studied your armor, for instance) don't be a jerk about it. Don't argue. On the one hand, be humble, on the other hand, grasp at every opportunity at leadership. If you fail, try again.
Contrary to what others might say, Volunteer for EVERTHING. Regardless of how p*ssed off, how tired, how demoralised you are, stick your hand up as soon as you hear words like "I need some, , , " Don't be a slimeball and wait until you hear what the mission is, just DO IT.
Any chance you have to get the much loathed and universally despised kitchen duty, take it.
Watch the cooks, learn to do what they do. They may come a time, when you might be able to quicky whip up a hot meal for your comrades, and boy, is that a really welcomed skill when it
is needed.
Listen carefully to your Drill Sargents. They care about you, and their job is to do their best
to make sure you can accomplish the mission and get home alive. Do as you are told.
Me personally, I have a hard time doing what I am told for the most part, I never had a hard
time with this in the military (in a training cycle) because I knew the point was to save my
life in combat, and to save my comrades lives.
A lot of what you will do won't make a lot of sense, but the point really is to save your life
in combat. Right now, you may not think that finding that last bit of filth under the rim of
the latrine has anything to do with anything, but you'd be wrong.
If you are at all squared away, your comrades are going to look to you for clues as to what they
should do when things don't add up, or make sense. Folks, by and large, are herd animals. When
things go a little nutz, they look for folks to take charge, so they don't have to. Take charge in training as often as you can. Try everything you can, screw up in training as much as you can, so that you don't screw up on the battlefield.
When i say do as you are told, I don't mean be a little b*ttkisser, I mean listen to your orders, and
execute them. When possible, or even when not possible, make mistakes, in the vein of raiding
other training units and other mischief. Accept your punishment when caught,
and NEVER EVER EVER EVER give up your comrades after you have been caught.
Go to this page:

and LEARN IT BY HEART, study on it, meditate on it.
Have as much fun as you can, don't be afraid to make mistakes, the time to make mistakes is
in training, your drills will square you away, don't worry, they will take care of you.
If you are a person of faith, any faith at all, go to your church, or place of worship, seek out
your elders for counsel. There will be church elders who are combat veterans, there always are.
They will have some tips for you.
You will never be able to get along with everyone, no one can. But be professional in disagreements and NEVER take it personally. A lot of fatal mistakes on the battlefield
result from anger based decisions, or are based in disrespectful conduct.
Do not fear your enemy, but do respect your enemy.
Some of your drills will try to be your buddy, and some of them will be unfreak'n believable
bastards. Listen to all of them. Respect them, they work harder than you do, and they
are really tough, and no one is on the drill trail by accident. They are there, because they care,
and they want to save your life.
I've been alive long enough to be called granpa, and one of the most proudest moments in my life
was during graduation from infantry school, when a drill that I simply couldn't stand, that I (and
many others) had had a terrible time with, during the final inspection, told me "Dog3, I'd be
proud to serve with you anytime". He didn't say than to anyone else. Though I couldn't stand
this guy, to this day, I'd follow him to the gates of hell itself, and I have some idea what
that really means.
