I received an Article 15 and my PCS orders were canceled. Am I able to PCS after the punishment phase?

I wouldn't see why they'd prevent you from a PCS after your "punishment phase". They may be a bit more hesitant about letting you go. I would think it depends on what you did for the Article 15. I'm not going to ask because it's none of my business, nor is it anyone else's. Just be smart. Keep your nose clean, stay under the radar, soldier on and prove that you've learned from the experience. There will be plenty more opportunities for you and your career. A wise is NCO once told me that every good leader has been in trouble at least once..

SPC (Join to see) I feel like there should be a little more to this story than your PCS Orders getting canceled. I have yet to see an Article 15 get processed fast, and canceling a PCS isn't easy without proof.

I am guessing they took away your leave, or put your PCS on deferment. You should PCS after punishment phase, to the same duty location as you were set to go to.

It's normal to have your orders canceled when flagged and especially when approaching your PCS date because it is a non transferable flag.
Once the punishment phase is over you can contact your branch manager about your assignment. Depending on whether you've passed your original report date or the slot was for a different rank, your branch may or may not place you back on your original assignment and date.
