Do you think male Soldiers should know the female regulations in AR 670-1 just as much as the female herself?

Answer: Yes. Leadership or not, it is important to know both.

It isn't knowing the regulation as it is to research the regulation. A lot of AR 670-1 can be seen differently as the reg is so general. It is good to have it handy when it comes to understanding the rules! For the female aspects of the reg, knowing where to look to solve issues is a must. I have the reg as I have many on my iBook app.

They publish those regs so they can be referenced. The Army isn't ran on the tradition of oral history. Learn what you can but don't fear looking up a reg. Nobody can memorize it all. Know the basic and obvious, sure, but I don't think it's a knock on someone if they have to consult the regs to answer a specific question.
(I commented this same thing on someone else's post.)

Yes you should know the regarding for all soldiers

If you are in a leadership position, there is no question. But now you are getting away from the original subject.

YES! At my E5 board, one of the questions concerned the hem length of the female skirt. I later learned they asked the female's about the hem length for male trousers.

We have to know all standards as leaders of Soldiers! It is difficult when we change uniforms every five seconds, but hair length and such doesn't.

Absolutely SSG Mims, during my tenure I had female soldiers and any true leader needs to be well rounded in knowing all regulations.

I had an ole section chief (master sergeant)(E-7)(air force) that use to destroy any woman who was out of regs. Half the time they themselves didn't know the regs. It was awesome to seem him rip them on finger polish, hair, nail length, hair color, and even make up. Then we end up getting a Senior Master Sergeant (E-8) who was a former drill instructor for 8 years and her would not only back him up, but would call his wife who just made Chief (E-9) and the scream and the crying that would happen was amazing. Now I believe if you make it to and NCO rank then I think you should know it, or have the reg book close by.

Not so much male soldiers but NCOs and Officers period. Can't very well be a correcting NCO quoting AR 670-1 if you are an idiot with female uniforms. Ask any drill sergeant.
