At the risk of getting my head shot off again as I raise it above the parapet...
I was in the TA infantry before the RAF and for a short period the Infantry Training Centre at Catterick experimented with putting women in (TA-only) infantry roles. I can honestly say without glee that they struggled to reach the basic standards of fitness while carrying bergans, webbing and rifle over a week's field exercise. This was the mid-90s well before all roles were opened up.
Applying this experience to downed aircrew is hard as it is different to the infantry role (on your own (stand fast RW/ME), no heavy kit, possibly deep sausage-side, trying to E&E instead of actively closing with the enemy, etc). And I was never trained in hand-to-hand knife fighting...
