These are mercenaries, not volunteers lmao.
All labor is voluntarily and mutually agreed upon by both parties! 
Let a thousand lancets boom.
I wonder if they will be trialed like those people that went to fight for ISIS
This is the best summary I could come up with:
Leaked documents last year confirmed that some NATO countries — including the United States, Britain and France — had deployed small numbers of special forces and military advisers to Ukraine in unspecified roles probably related to logistical support work and training.
The United States’ CIA has funded and partially equipped a sprawling network of spy bases across Ukraine that aid Kyiv’s efforts to track Russian troop movements and target the Kremlin’s prized military assets.
After Russia launched its full-scale invasion of Ukraine two years ago, thousands of sympathetic volunteers — largely from the West and post-Soviet states — enlisted under Kyiv’s banner.
Other volunteer brigades fighting for Ukraine include detachments of Belarusian fighters opposed to the Putin-backed dictatorship in Minsk, anti-Kremlin Russians and ethnically Turkic nationals from Russia, and post-Soviet states like Kazakhstan and Kyrgyzstan.
Infamously, soldiers from the Wagner organization, a state-backed mercenary company, participated in what was a short-lived putsch last June amid internal anger over the management of the war.
Their presence belies the constant state propaganda produced by the Kremlin, detailing accounts of Russian forces capturing or “eliminating” foreign mercenaries fighting for Ukraine in a bid to underscore the supposed illegitimacy of Kyiv’s government.
The original article contains 1,345 words, the summary contains 198 words. Saved 85%. I'm a bot and I'm open source!
After Russia launched its full-scale invasion
The media keeps repeating this specific phrase. "Full scale". Have to wonder why
A good point of contrast is the U.S. invasions of Iraq and Afghanistan. The media never had this type of lockstep "and remember to emphasize it's a really bad invasion" coverage.
The Iraq invasion comparison is what gets me. USA has committed something like three times more military to Iraq than Russia did to Ukraine. And that's not counting various private contractors. But I guess that wasn't a "full scale invasion"?
The unprovoked full-scale imperialist invasion of a sovereign state.
People are fed these words that they don't understand the definitions of so that they can try to seem smart. I make a point of asking them what they mean by "sovereign" or "imperialist" etc. They get all sweaty when you do that.
