What I'd like to see them to do is change the PT test to something more relevant/useful -- but make it equally difficult for both. Part of the reason for the (US) disparity is that the tested items are biased toward male structure.
For a grunt, you need to able to sprint repetitively with a load. You need to be able to do an extremely long march with a load. And you need to not be a heart attack waiting to happen.
Three tests: two physical, one physiological (in three parts).
Physiological test 1a. Blood pressure.
Physical test one: with 20 pound ruck/vest load plus rifle and helmet, from prone position get up, sprint 10 meters, drop to prone. Repeat ten times within determined period of time.
Physiological test 1b. Blood pressure, timed to determine when pressure returns to 1a plus 5%.
Physical test two: With 40 pound ruck/vest load plus rifle and helmet, 5 miles within predetermined period of time.
Physiological test 1c. See test 1b.
Physiological tests: resting blood pressure cannot be above (limit to be determined). blood pressure must drop to level in acceptable time.
Fitness and basic requirements. Just my two cents.
