How much historical precedence is there for soldiers (and even civilians) of a neutral country volunteering to fight in another country’s war?

I can’t think of ever hearing about something like that happening in previous wars. But I’m not a historian.

I’m from the US and I find it interesting to hear of veterans volunteering for the Ukrainian army. It is crazy to me that I also read about a PA trucker with no combat experience who went to volunteer.

Yes, it's not exactly common but there is a long history of such volunteers. I gave an outline here.
