Should can't women be topless if men can?

I have never complained about women Flashing their Breasts

why is this in the military category 

Yes. In some places they can.

In Bondi an  Australia beach being Topless in 100% legal

Good point.  Most guys these days need a bra.

most of my partners in high school were topless

Oh, my God...

It's not illegal in my country.

That's the law in Canada. I think the SCOC decided that women could go topless because men can.
