90% of all the problems within gundam crews are caused by women being retards.
Why do they even employ them when this is so obvious?
A ship full of all men is a ship with low morale. Including young, single support staff on a vessel is a great way to keep your men's spirits high, and ensure they will lay down their lives for the sake of the crew.
I'm sure there are other options to raise morale.
None that are quite as effective, honestly. And you don't want there to be dudes in dresses. The idea is that there should be as little actual sex or contact as possible. That's why you want medical and communications officers as your crew's women. They should outrank most men. There needs to be a reason why your men aren't fighting over the girls and relationship drama isn't causing issues.
I realise that.But in the OP i am mainly talking about the pilots or commanding officers.
