The average female Army recruit is 4.8 inches shorter, 31.7 pounds lighter, has 37.4 fewer pounds of muscle, and 5.7 more pounds of fat than the average male recruit. She has only 55 percent of the upper-body strength and 72 percent of the lower-body strength... An Army study of 124 men and 186 women done in 1988 found that women are more than twice as likely to suffer leg injuries and nearly five times as likely to suffer fractures as men.

The Commission heard an abundance of expert testimony about the physical differences between men and women that can be summarized as follows:

Women’s aerobic capacity is significantly lower, meaning they cannot carry as much as far as fast as men, and they are more susceptible to fatigue.

In terms of physical capability, the upper five percent of women are at the level of the male median. The average 20-to-30 year-old woman has the same aerobic capacity as a 50 year-old man.

Lt Col. William Gregor, United States Army, testified before the Commission regarding a survey he conducted at an Army ROTC Advanced Summer Camp on 623 women and 3540 men.... Evidence Gregor presented to the Commission includes:

(a) Using the standard Army Physical Fitness Test, he found that the upper quintile of women at West point achieved scores on the test equivalent to the bottom quintile of men.
[...]
(c) Only 21 women out of the initial 623 (3.4%) achieved a score equal to the male mean score of 260.

(d) On the push-up test, only seven percent of women can meet a score of 60, while 78 percent of men exceed it.

(e) Adopting a male standard of fitness at West Point would mean 70 percent of the women he studied would be separated as failures at the end of their junior year, only three percent would be eligible for the Recondo badge, and not one would receive the Army Physical Fitness badge.

Non-deployability briefings before the Commission showed that women were three times more non-deployable than men, primarily due to pregnancy, during Operations Desert Shield and Storm. According to Navy Captain Martha Whitehead’s testimony before the Commission, ‘the primary reason for the women being unable to deploy was pregnancy, that representing 47 percent of the women who could not deploy.’

I was stunned. The Army was a vast day-care center, full of unmarried teen-age mothers using it as a welfare home. I took training seriously and really tried to keep up with the men. I found I couldn’t. It wasn’t even close. I had no idea the difference in physical ability was so huge. There were always crowds of women sitting out exercises or on crutches from training injuries.

They [the Army] were so scared of sexual harassment that women weren’t allowed to go anywhere without another woman along. They called them ‘Battle Buddies.’ It was crazy. I was twenty-six years old but I couldn’t go to the bathroom by myself.

After extensive research, Canada has found little evidence to support the integration of women into ground units. Of 103 Canadian women who volunteered to joint infantry units, only one graduated the initial training course. The Canadian experience corroborates the testimony of LTC Gregor, who said the odds of selecting a woman matching the physical size and strength of the average male are more than 130-to-1.

One-third of 450 female soldiers surveyed indicated that they experienced problematic urinary incontinence during exercise and field training activities. The other crucial finding of the survey was probably that 13.3% of the respondents restricted fluids significantly while participating in field exercises. (p. 690)

Kessler et al found that the lifetime prevalence of PTSD in the United States was twice as high among women. (p. 661)

The Female of the Species

by Rudyard Kipling, 1911
 
When the Himalayan peasant meets the he-bear in his pride,
He shouts to scare the monster, who will often turn aside.
But the she-bear thus accosted rends the peasant tooth and nail.
For the female of the species is more deadly than the male.

When Nag the basking cobra hears the careless foot of man,
He will sometimes wriggle sideways and avoid it if he can.
But his mate makes no such motion where she camps beside the trail.
For the female of the species is more deadly than the male.

When the early Jesuit fathers preached to Hurons and Choctaws,
They prayed to be delivered from the vengeance of the squaws.
’Twas the women, not the warriors, turned those stark enthusiasts pale.
For the female of the species is more deadly than the male.

Man’s timid heart is bursting with the things he must not say,
For the Woman that God gave him isn’t his to give away;
But when hunter meets with husbands, each confirms the other’s tale –
The female of the species is more deadly than the male.

Man, a bear in most relations – worm and savage otherwise, –
Man propounds negotiations, Man accepts the compromise.
Very rarely will he squarely push the logic of a fact
To its ultimate conclusion in unmitigated act.

Fear, or foolishness, impels him, ere he lay the wicked low,
To concede some form of trial even to his fiercest foe.
Mirth obscene diverts his anger – Doubt and Pity oft perplex
Him in dealing with an issue – to the scandal of The Sex!

But the Woman that God gave him, every fibre of her frame
Proves her launched for one sole issue, armed and engined for the same,
And to serve that single issue, lest the generations fail,
The female of the species must be deadlier than the male.

She who faces Death by torture for each life beneath her breast
May not deal in doubt or pity – must not swerve for fact or jest.
These be purely male diversions – not in these her honour dwells.
She the Other Law we live by, is that Law and nothing else.

She can bring no more to living than the powers that make her great
As the Mother of the Infant and the Mistress of the Mate.
And when Babe and Man are lacking and she strides unclaimed to claim
Her right as femme (and baron), her equipment is the same.

She is wedded to convictions – in default of grosser ties;
Her contentions are her children, Heaven help him who denies! –
He will meet no suave discussion, but the instant, white-hot, wild,
Wakened female of the species warring as for spouse and child.

Unprovoked and awful charges – even so the she-bear fights,
Speech that drips, corrodes, and poisons – even so the cobra bites,
Scientific vivisection of one nerve till it is raw
And the victim writhes in anguish – like the Jesuit with the squaw!

So it comes that Man, the coward, when he gathers to confer
With his fellow-braves in council, dare not leave a place for her
Where, at war with Life and Conscience, he uplifts his erring hands
To some God of Abstract Justice – which no woman understands.

And Man knows it! Knows, moreover, that the Woman that God gave him
Must command but may not govern – shall enthrall but not enslave him.
And She knows, because She warns him, and Her instincts never fail,
That the Female of Her Species is more deadly than the Male.
