E6 oml list and how do you get hard slotted? Also would they skip me because I only have ssd 2 done, but not alc?

You have SLC2 completed, you should be on the OML for ALC.

MILPER MSG 16-089: Select-Train-Educate-Promote (STEP) NCOPDS Scheduling Procedures
Advanced Leaders Course (ALC) is a branch-specific course that provides Soldiers selected for promotion to SSG an opportunity to enhance leadership, technical skill, tactical expertise and experience needed to lead squad-size units.
Completion of SSD Level 2 is a prerequisite for attendance at ALC.
Priority goes to SSG and SGT(P) who have not yet attended.
Effective January 1, 2016, promotion to SSG requires Soldiers to complete ALC before pinning on the rank of SSG.

If you are completely administratively eligible and your packet is complete, a decentralized board will vote on your packet this spring. If they recommend you, you will be on the OML in June. When that publishes, everyone on your OML with ALC complete will be offered before they offer to anyone on the list without ALC.
So yes, they will initially "skip" you to exhaust the list of ALC grads first.
Depending on how many vacant E6 positions there are currently in your state for your MOS, and how many more they create by promoting E6s to E7 before starting the E6 list, that is how many promotions will happen in your MOS in your state this year.
"Hard slotted" or transferring an E5 to an E6 position happens after that E5 has accepted that E6 promotion offer, or if there are still E6 vacancies remaining after that OML is exhausted, then an E5 can be transferred to an E6 vacancy to take that role.
