Nicely put Genstabler, in order to maintain the current ban on women serving in infantry units the Armed Forces must show that there would be a degredation of operational capability. Some of the points made elsewhere in this thread are subjective but the fitness test is absolute, therefore must be gender neutral- no ifs or buts and no change to allow more women to pass. If they want to join the infantry then they do exactly what the men do, if they can't crack it they get removed just like a man would.
Melchett good idea about the current test but why not remove the age difference as well?
