It's great, but as warfare has now changed I think opening up infantry roles to women who will never be used is why they have done it.
Except for 1,2 and 3 para recently no infantry units have been used in theatre recently since the formal withdraw of Afghan, and they are unlikely to return.
Trench warfare has ended, mass infantry warfare has ended. I mean why send a man/woman when you can pilot a drone from Berkshire over Syrian airspace and kill people?
Women have always been able to join SRR (which is a branch of the special forces) it has now been opened up to SAS and SBS, I can tell you know I don't expect any woman to be selected.
Selection for the special forces is unlike anything else, you could pass ever physical and mental test and they have the right to turn round and say "no, thank you". You also only get 2 attempts at selection so basically they say no twice your done for. They also do not have to give a reason, we have had friends that have just been told "your not the right fit".
The hill stage I can see women passing, the jungle phase I can see woman passing it's escape and evade which will fail most, then followed by directing staff saying no.
It is what it is. Warfare has changed, no woman has ever passed P company (selection for paratroopers) they have however passed for the Royal Marines. I think you'll end up with a small number of women as RM but I doubt they would then get put forward for a SFSG (special forces support group) role, they could however opt to do SBS selection, but I fear the same would happen DS (directing staff) will fail them.
Personally I think opening up the general army/Navy/RAF roles is great but those women and men aren't being used. RAF, SFSG and SF are the busiest operational roles at present, and 90% of those roles already accepted women.
