In the majority of cases in the workplace, men and women can compete on a equal footing. In some cases - where compassion and emotional intelligence are required, women are usually better. In other cases, for example when brute strength and resilience to cold are concerned men are usually better. But combat is not an equal opportunities employer.
When we have women competing against men on an equal basis in combative sports, and winning - Rugby, Boxing, MMA - then we should accept women in an infantry (close with the enemy and kill them) role. Until then, it is just PC rubbish.
A women boxer in a ring with a male heavyweight boxer would die. The best female woman Rugby players, being tackled by an All Black, would equally be badly hurt and might die. Battlefields and our enemies do not make allowances for the type, weight, strength and gender of the soldiers they fight against. We cannot put our small soldiers against other enemy small soldiers... It is just a winner takes all fight.
Natural selection and evolution has not caught up with our political agenda...
