Grip is less the issue it's overall that does have problems.
Female civilian shooters are just as good as there male counterparts.
The problems have been pointed to are when you add in almost 200 pounds of other kit. There are also lesser issues such as changes in body shape that effect fit for modern body armor and general hygiene.
Gotcha, but would you say those 200 pounds of kit are really necessary for mission, or is it more a matter of doctrine?
What I'm wondering is, with the appropriate training and doctrine, could a company of all-female infantry be as effective as a company of males?
