Well, maybe I don't understand "dumb down," but the Canadian Army web site gives the following standards in passing their "physical fitness" test:
Under 35 year old male................female.
Shuttle runs ....6.....................4
Push ups ........19....................9
Sit ups .........19 ...................15
Hand grip ......75 kg. ................ 50 kg.
In my opinion, such disparity constitutes difference in standards.
It may be that the Canadians have become PC and compromised their standards. If they have, it does not bode well for the units with the women assigned.
In the USN, females are assigned to certain ratings jobs, but the guys in their division or detachment are well aware of the tasks their female shipmate can do and the jobs that she cannot. Therefore, males have to pickup the slack for the jobs Suzie Sailor cannot do.
Of course, Suzie Sailor always can exercise the “option” by getting pregnant. Once she's reported as pregnant, she's given light duty and transferred off the ship to a shore station at the first opportunity until the child is born. She's usually retained at the shore base for up to a year so she can care for her child. Meanwhile, back at her old duty station, NO replacement sailor is assigned to the position Suzie's pregnancy opened up. The other sailors are left to shoulder her load in addition to their usual work.
