Kingsley Browne

“Inclusion of women creates a segment of the military that is physically weaker, more prone to injury (both physical and psychological), less physically aggressive, able to withstand less pain, less willing to take physical risks, less motivated to kill, less likely to be available to deploy when ordered to, more expensive to recruit, and less likely to remain in the service even for the length of their initial contracts. Women are placed in units with men who do not trust them with their lives and who do not bond with them the way that they do with other men. The groups into which they are introduced become less disciplined and more subject to conflict related to sexual jealousy and sexual frustration, and men receive less rigorous training because of their presence. Officers and NCOs must divert attention from their central missions to cope with the “drama” that sexual integration brings, and they must reassign physical tasks (or do them themselves) because women cannot get them done fast enough, if at all. Men who have traditionally been drawn to the military because of its appeal to their masculinity now find that the military tries to cure them of it to make the environment more comfortable for women.”
