Zardoz,
I hope my comments will contribute to your survival (thinking),
though they may anger you, in the short term.

That women work in a police force and in the army, does not
provide much evidence that they are effective in those industries.
Standards were lowered so women could qualify.
We live in a PC world, where the deficiencies of women will
be overlooked, so a lot of evidence of female deficiencies,
never surfaces.

On the job, criminals know that a women cop is backed up
by men. OTOH, I do agree that some young macho male cops
should use their brains more, and muscles less, like many
female cops naturally do.

There are instances of women who have the physical and
mental ability to survive solo; this is not good evidence that
many women have this ability, or even that they could acquire
this ability.
A case where any solo woman gains a differential advantage:
the male(s) underestimate the woman. It would be a bad idea
for a woman to count on this, however. Also, accomplished
and skilled women might be underestimating these bad guys.

My belief.
Small groups are the best protection for both sexes.
For a small group survival, during hostilities, women are key.
Why?
For close fighting,
the bad guys will be focusing on men, killing the men, or out
maneuvering the men.
With the focus off the women, the women can attack the
bad guys from angles of advantage.
For longer range fighting,
the women will not have any better angles of attack,
(usually), but with women shooting, firepower would
be doubled; a rude surprise for the attackers.

Natural male aggression is needed for survival but
it can get you into trouble, especially if the enemy exploits
you and your game. Many battles have been lost on the
"undisciplined" aggression of a small group. Watch the video
(or read the book) We Were Soldiers with Mel Gibson; a
small sub-group chased NVA/VC and got cut off, rendering
artillery and bombing support almost useless. Then, very
bad things happened.

With women in a group, men are less likely to
pursue bad guys and get ambushed or into other trouble.
The men (even bachelors) will naturally stay closer to the
group; but additionally women will discuss with the men
that there is a great danger when pursuing an enemy.
