It's a war. Normal rules to not apply. If you are ever in one, you will want a weapon, trust me.

Lulz - that’s all well and good, except that gets paid mostly lip service even by the professional militaries, who are the ones who have the most to lose by not following the rules.

Civilians do what they need to do to survive and protect their loved ones. If that means shivving a soldier in the back while pretending to be unarmed, so be it.

Having guns is way better than civilians usually get.

Yea, they can do that but i think it is a war crime. Not sure thou im not lawyer.

Anyway it probably confuses soldiers so they start shooting civilians.

They do that anyway. And war crimes are solidly in the class of ‘if you win, it’s not a crime’ unfortunately. For example, the US (as much as it tries) often commits what are clearly war crimes, and it’s crickets.

Unlawful combatants aren't protected by the laws of war, they're protected by the laws of the land they are in. I think you'd be surprised at how lenient the laws of the land can be for people who technically commit crimes like murder against invading forces.

You wear IFF coloured bands. From photos I've seen the Ukrainians are using yellow arm bands, and Russians white leg bands.

They are trained by the local defense organization.
