All armies are either mercenaries or slave. Or, to use other parlance, volunteers or conscripted. Mercenaries generally behave better and make better soldiers
These aren’t “professional” mercenaries.
These are “mercenaries” in the sense that they’re paid by Putin and fight but they’re mostly prisoners who will have their criminal records expunged.
The “professional” mercenaries are mostly fighting on the Ukraine side.
What an idiotic post.
