What is the extent of an article 15?

Not a JAGO. BUT...you asked. You know what I was by my profile. (knuckle dragging, ramp jumping, fast roping,80lbs on my back etc )However; when the 1SGT or the SGM walked in (my time from 77 to 2001 for me) and said we got a problem I listened. If they told me they wanted a ART 15 signed by me I knew they wanted this individual's career trashed. They wanted him to be a non survivor of the next promotion board. They also wanted his TS/SCI non renewed (as a general rule it was trashed). Anyway due to the current generational war he/she may survive if they get top blocked across the board and a probably V somewhere on their chest. In my time it was over. If you're good and FU'ed once or twice and they want to save you they start out with weeks long extra duty training (volunteered of course), a 1SG's ART 15. That is in a local file that is dump when he leaves. Many over jubilant or usually the "energetic idiot" (AKA 2nd LT ) comes screaming for a ART 15 the senior NONCOMS can normally control him. If he worth saving!!
Don't get me wrong; somethings are not fixable and should not be fixable such as rape or traitors. FTR!! Can't make a formation? What is that under now? ART 88? Either way, you need to pull your head out of your ass and tell your chain of command what a knuckle head you was and will perform like a trooper that a platoon is depending on him not to get them killed. I almost can see one of my older seniors talking to you out back for a few. Some units such as TEIR 1 and 2 units don't have time. Canned and gone in 24 hours. Certain rifle companies at Fort's Benning, Stewart Army Airfield, and in Washington state may be a little less understanding with a foot print on your sorry ass.

RLTW!!

Lol use the force young Jedi...

As a prior enlisted Soldier, then Platoon Leader, Company Commander, etc., my Soldiers need to be where I want/need them to, when I want/need them to. If you can't practice that in AIT, you'll be no good for anyone in your first assignment. Remember why you enlisted, follow the sage advice given by the others in this thread, and get your act together. It sounds like you acknowledge the offense(s), so taking responsibility is one more step toward maturity. My group at AOBC once had to report for a full TA-50 layout at 0300, after some of our group didn't have their act together for the layout the day before. We were headed out on a 10-day field exercise and some (thankfully not me) needed a foot in the a-- as a wakeup call. You're in the Army, and if they tell you to be somewhere at a certain time, be it 1200 or 0200, there's a reason. Take the punishment if deserved, learn the lesson, and drive on. As others said, it shouldn't follow you past AIT.

Ask yourself this, if you showed up to work late in the civilian world would you be punished? Yes, your bosses may ask you why, looking for a reason, but, if it becomes a habit you will be terminated. The military is no different, with one exception, they, the military, will continue to give you chances, using none judicial punishment, initially, as a warning to correct your behavior. If you still continue this behavior, they will then lead to judicial punishment to correct your behavior under UCMJ. That is where you're at now. Trust me, showing up to work on time is just as big of a work requirement outside the military, as it is inside the military.

It blows my mind how you can even think about getting promoted when you can't even manage to make it to formation on time.

If I were your 1SG , I'd help you develop that skill by confining your young ass to the barracks.

Why are you always late? The easiest thing in the military to do is be where you are suppose to be on time.

Well from someone who received an Article 15 and reduce to E4; you can be Discharge also. So stop doing what you are doing and show your command you wanna be there and stop wasting their time!

I can't tell you what exactly follows you around with each service. I will give you my experience with NJP. I hated sending any of my sailors to NJP, I viewed it as a failure of my leadership. Hence, I only sent 3 people to NJP over my career.

That being said, sometimes there is no other choice but to send them to NJP. I looked at it this way.... the sailor screwed up, NJP was help, punishment was given, now there is a clean slate. That is what I want to stress to you. Once you are done with punishment or whatever, you will have a clean slate... USE IT! If you want to do well, then do well. Fix the issues you are having however you can, and be the best service member you can be. The service members to your left and right deserve that. If you can't do that, then get out. This isn't a game, and more and more it is getting more dangerous, even for non-combat troops (look at the Ship and aircraft accidents lately).

Think about the fact how many senior officers and enlisted are giving you advice on your situation. You are lucky. They are telling you the roadmap. It is up to you to use it. I will say the fact that you are at least asking is a positive to me. Best of luck to you!

How have things worked out for you since you first posted this question???

At 39, I was 10th in this National Guard Unit scholastically, running the steaks (my phase 1 class beat the living hell out of the phase 2 at AT, I had an 80 SQT...not bad for a NG, past a PT test first time in 20 years and just weeks before my Article 15, my C.O. complimented me in front of the company. Well, I reported as I always did, down at the armory one night, and I was given an Article 15, (my only one), for being AWOL...under the guise of "having a bad hair cut!"
Along with a Counseling Statement ...gee, shouldn't that have been done before the article 15? Since I had a bad hair cut, I was considered AWOL...I told those Courtney Massengale stereo types who ran the unit "I never went AWOL during The Vietnam Era, went I was RA...when Desertion Happened Every 5 Mineuts." remember? But, that didn't count any more, back in 1990. (I was a Veteran, when it wasn't popular!)
To this day, I never cared for the phrasing.
