Since you aren't baptized, if you work on a military base, you will not be eligible to be an unbaptized publisher nor qualified to enroll on the Theocratic Ministry School. It has to do with the neutrality issue.
You mentioned about sisters who are already publishers who are married to active duty military. If they were to work on base, then they would be excommunicated from the congregation because it means that they would have disassociated themselves by breaking the neutrality issue.
If you elect to work on base, then it will create a buffer for you in terms of congregational committments. You will be prevented to have any active role in the Kingdom Hall. Thus, your study conductor will then have an "unprogressive" Bible study. Great for you if you want to just slip away.
