At the Cross and before the throne there are no differences or groups. In this life, Paul clearly laid out several chains of command or organizational groupings. We all have roles.
God
Man Angels Demons
Woman
Children
In business
Boss Should be Men only. Proverbs 31 can have cottage industries, buy real estate, but not bosses.
Worker
Government
Kings/Rulers Men Only
Citizens
Church
Pastors/Elders Men only
Deacons Men Only
Members
Military is definitely a rank organization that should be made up of only males. Once read where at any given time 1/3 of sailors are non-deployable due to pregnancy. Female captives will suffer far worse than males. It's all fun and games until you are a POW. 5'4" female, 130 lbs will not be able to drag or fireman carry a 6' 2", 180 lb male to safety if wounded.
