As a researcher, of course I'm going to say that we need more research, but the answer is to figure out which parts of the traditional aspects of physical tests to differentiate between the combat roles are necessary, and which are kind of left over from a more traditional military evaluation of what it means to be a soldier. There are definitely baseline fitness aspects to jobs like being in the infantry or being in the army combat arms. There's no way of getting around that. You have to be able to lift things over your head and all sorts of other things that could be challenging for some women to achieve. The difference is that not every requirement has been fully evaluated as being necessary.
To know which parts of traditional soldiering are necessary and which parts of traditional soldiering are just kind of traditional requires pretty honest research. I say “honest” because sometimes the answers to those questions disappoint people like me, who are strong advocates for women in the combat arms, for example. If the research tells me that, actually, being able to lift 65 pounds over my head is a requirement for the job, I'm not necessarily going to like that answer, but I think for the research to be genuine, and for it to treat people in the military with fairness, we have to be ready to find out things that we don't necessarily want to find out as advocates and researchers.
