Swede here, makes perfect sense, a woman can aim and pull the trigger just as easily as a man.
I had to show up for mustering back in 2006 or so, I failed the hearing test and didn't do military service.
Back then only men HAD to muster, women were allowed to, then the government removed conscription and moved to a professional military.
However as tensions in the region conscription has been reinstated, but works in a different way.
Now you get a form to fill out in the year you become 18 regardless of gender, it is required to fill out the form, and if the military is interested in you, you will be called to muster, passing that, you will be selected for military service.
