The weapon is hung low and you'll also notice it has para cord tied to the strap, this is because it allows the gun to be slung with the natural firing position (trigger and magazine facing down) if it was slung from the fitted bales this can't be done.
The method is, that you move your right hand through the strap, dip you shoulder and the weapon will swing to the front and hang at about the length of you arms, which in a quick movement allows you to scoop it up, slot the magazine in, cock it before it is in your shoulder. They are trained to do it and it should take no longer than 3 seconds to first shot. (In this case it's not likely to happen because she's holding her hand bag, but these can be just a lethal in the wrong hands.)
Serving Israeli soldiers have their weapon with them at all times, even on leave, so they spend a lot of timing hanging around with it, so it needs to be comfortable but also accessible.
One of the joys of choosing to marry your Israeli girlfriend so that you can stay in the country (or together should I say), results in draft papers landing on you doorstep
This would be the time to add a link to one of those You Tube videos of girls in the IDF, I'll leave it to one of you to do that because the handbag is always loaded.
