I've learned that mercenaries are the paid ones, people like Russian Wagner etc.
The ones on the Ukrainian side are "volunteers".
But sure, fair enough - a lot of those guys were volunteers. Either way, they got hammered as did the ones in the Odessa hotel (and likely others).
Here's another "English as a foreign language" tip:
Every time you come across a word you are not sure about, look it up.
You'll be amazed at how much your English improves, both reading comprehension and writing.
Or you didn't know that Ukrainian Foreign Legion unlike Russian Wagner and certain other aren't paid.
Either way it means you either don't master English completely, or you aren't up to snuff on what is going on.
