Is it standard or even typical as a form of disciplinary action for an NCO to call a soldier's parents to complain about the service member?

No, that's not normal for any job to do that. Frankly it's extremely unprofessional.

No they are adults at this time in there life and should be responsible for their own actions.

I have never heard of that before. Honestly, I have no problem with it either. If you are going to act like a child be expected to be treated like one. Even if you say you are a "grown man and can face the legal and moral repercussions". Grown enough to face the consequences, but not grown enough to not commit the offenses in the first place. Maybe a little embarrassment and advice from your family is what you need to not repeat your actions. One of the worst things I could think of is disappointing my parents or bringing shame to the family.

Well being from the great state of Texas I would have refused to give my family's number and then let her know I stepped on my richard and am prepared to take whatever punishment is decided upon. This is a tough scenario since I never served with woman,However there was a e5 from my home town who broke bread with my wife and I in my off post housing.She returned to Houston for her mothers health and friday night while out with my team, This sgt on CQ duty took a call from my wife telling her I was hitting the strip clubs while doing coke and drinking and he thought he saw me with a hooker. All untrue except for some beer.. fortunately , My wife knew me to always be honest with her and I was able to smooth those feathers. 2 weeks later young oh so clueless sgt.smith having enjoyed quite a few pitcher stumbled to the barracks from his POV and ran right into a world of hurt . This man was so unliked that while I tried dislodge all that guilt trapped in his airway with repeated blows to the ribs and head, to assist him since he was clearly having trouble breathing. and other soldiers did the same. a practice you just dont see in a combat unit. when he had me called into the CO's office on Monday morning I luckily had 15 statement's in my cargo pocket explaining how he had attacked me in a fit of rage and jealousy clearly upset about his lack of a penis.
strangely; some of those soldiers had been off post that night. curious! and when asked about my lack of wounds by comparison,I calmly replied that when a man fears for his life ...like I did ...you move fast and get lucky . Now I know this doesn't help you young E2 unless I spell it out. learn the system, and be so squared away that when you do step on it, everyone is not perched waiting tc come down on you like a ton of bricks . DBAP ( don't be a pussy) and for God's sake quit arguing with MP's when you been drinking

What your sergeant did is not only unprofessional but in my opinion beyond military SOP. Your and adult in a military organization. Not some misbehaving child in school. Your sergeant has some serious supervisory issues that need to be addressed by her superior. Maybe even some retraining.
GOOD LUCK,

If this had been posted on April 1st I'd know for sure if this post is real or if the poster is just "messing" with us. If this is real then the military (the Army for sure) is in a downward spiral.

I never contacted a soldier’s family to correct a behavior problem. My leadership style was to become the father figure, if possible, for young soldiers (18-20 year olds or just immature). I used monthly counseling to address poor behavior and recognize good behavior.
I wasn’t able to save all of my problem soldiers, but a lot of them responded well.
What ever I did served me well. I had successful tenures as squad leader, ply sgt, and 1st sgt.
I did contact a soldier’s family and encourage participation when one of my troops was being promoted or awarded.
Keeping up with monthly counseling and coaching was a lot of work, but I don’t regret it. In 22 years, I only had 3 that just wouldn’t respond and suffered the consequences.

No this is not a Standard procedure by the military but this is just a courtursy By that SFC not reconmand you to be kicked out the military, SFC is hoping that you will change your attitude by calling your parents in your presence and by the way, She already knew your Parent numbers and she wanted you to be aware of that. You should say thank you to that SFC when you see her or if she is your drill instructor, you should volunteer of every thing she has to offer for that day. Have repect for yourself, your family and the unit and once you understant that all is going to be well for you during and after your miliary career. I served proudly and discharged honorablely, I have good and bad time serving but I always maintain discipline toward myself and all appointed above me.

Here is a better answer I thought of after my original response:

Either A: The soldier is an adult, in which case why would you involve the parents?

Or B: The US is guilty of using child soldiers.

Consider the possible fuck-ups involved, too. In my time, there were many people including myself who left home for the service because we didn't want to have to put up with our parents. Since being in a painful situation one cannot escape is one reason for suicide, making ones situation (with parents) inescapable by calling them in, is a potential reason for someone getting pushed over the line.

And, why in hell would that even occur to anybody? It's egregious overreach of authority. I bet there is not one NCO, officer, or any other leadership school anywhere in any of the services that promulgates getting in touch with the parents as a means of discipline.

Your detachment SFC could have simply left it at the reprimand but the fact that she chose to seek other avenues to get you on the straight and narrow tells me that she thinks you have the potential for bigger things and as such she used all the tools in her tool box. Look at it that way and drive on. Climb to glory.
