The review, launched in May, has rejected the long-held view that mixed close ground combat units would have an adverse effect on team cohesion, which the report recognises as a vital part of the combat effectiveness of the team.
Other social or psychological factors were considered but not seen as an absolute bar to women in combat roles. The report doesn't mention the alleged female "lack of killer instinct", although it does seek to address the nature and character of conflict.
It also calls for further research into the physiological (physical) demands placed on those in close combat roles before a final decision is made on lifting the current exclusion on women.
