Any person who, on grounds of conscience, refuses to render military service involving the use of arms may be required to perform alternative service.
So men can refuse service at arms, but they can't refuse service, so how is that better ? Either way you're still drafted into war. Possibly into medical service as well. So it's not harsher, it's the same or worse, because you could be drafted to maintenance near the front lines, whereas medical is usually a ways back. Or as a woman you could volunteer to maintenance, logistics or recruitment before being drafted, then you're not forced into medical. You're likely not even put near the front lines as a woman.
So your statement that it is harsher on women is not correct. It's actually quite insensitive for the men who die in the front lines for the country.
No, i meant field medic. As in, giving first aid in helicopters or trucks as they drive away ferrying the wounded from the front lines, brought by their comrades. These are jobs that traditionally they don't give to women. They put women in the hospitals on the back and use men in the transportation and first aid, although sometimes women do volunteer to do this job like it happened in Ukraine.
As for a mechanic, if you're fixing an anti air system or a tank, you're pretty much next to the frontlines. You're just not shooting at the enemy, but you're still shot at by artillery or missiles. Combat engineers would be shooting at the enemy, but maintenance personnel are not. Those are specialized military personnel, not draftees. They're not deployed to push a frontline or defend a position, so they're not really combat roles. Although I'm not completely sure about it and if someone knows more about this than me, I'd sure like to learn about it.
Being in medical doesn't necessarily mean you will be taking care of shredded soldiers. There's tons of jobs in medical, such as ressuply of medicine cabinets, transportation of medical equipment to and from medical rooms, transportation of sick people in medical beds, post operation medicine, feeding and bathing soldiers, etc. If you've got a weak stomach, they don't want to put you in a position where you would pass out, then they have to take care of you too. But i can appreciate that it's hard on women too, of course. Nobody deserves the misery that war brings.
When you're drafted though, you're screwed whether you're a man or a woman. My father volunteered when my country was at war and they started drafting people so he could avoid the frontlines and got a real nice job working in long range radar maintenance. I think I'd probably do the same if i were in that position. You get to pick where you go if you volunteer.
