But per strength: I don't think it's acceptable to have different standards - I think - in regard to military standards - they should be EQUAL in their strength and abilities. Not hair styles and every little detail - but where it matters most, yes.
In general: when it comes to physical labor and the aspects related to it - if a woman wants to do the same job that is dominated by mostly men she should be able to DO the job without preferential treatment (etc). If she needs a back-up and an alternative plan for every job assignment then she needs to find a new job that's more suitable to her.
Just like men: many men can't cut the military standard, either - and they just don't graduate basic or boot.
