Women and combat duty

Women ought not to be recruited for combat duty. First of all, it is absolutely impractical. Two facilities for everything would be needed to set up. This would imply setting up two sleeping quarters, two sets of showers and two toilets. Thus, the real quantity of work would increase twofold. Secondly, troop movement would significantly slow down since the army would need more supplies and equipment in the field. Troops would lack the advantage of being prepared on the spot for a surprise attack. If an incredible amount of backup support is usually required only for men, it would definitely double with enrolled women in wartime. Last but not least, women are emotionally and physically weaker than men. Being in a genuine physical combat would imply having a lot of strength as well as courage, all of which women more often than never lack. To conclude, women should not carry out combat duty since they lack the strength to face it. Do you agree?
