Well, you might want to study the tactic of armed resistance before you get your name on their list.
Total Resistance is the name of the manual the Swiss wrote and all we need to know, really.
It makes a point that in war, there is no individual hope. Don't sign up, register or make yourself known for anything. You can be slave labor, later. They will use the list they liberate for the first slaves. The second set comes from those that cower and kowtow for the lists.
The conquers have no respect for the conquered. You are either resistance, amusement or a traitor. No Neutrality allowed. Don't try to go along. Your neighbors will kill you for that.
In short, in a invasion or insurrection your life is gone, now you are free to cower or fight....the only choices. We saw that in both the Independence and the Ciivl Wars here. You never know when the big bad guys show up in your yard.
They saw it in S. Korea, when the North invaded and they saw the same thing as Belgium changed hands a couple of times. That has got to be the very worse. The spies from both sides are watching everyone.
The Swiss were sure they would get overrun by Germany and then later the Soviets. So, there are none more prepared without shots fired, than the Swiss.
It makes a lot of sense to read the manual if you can find it.
