Since other commenters aren’t bothering to look into it at all:
Cuba says it has disrupted a scheme in Russia to recruit Cuban citizens to fight in Ukraine.
In a statement, Cuba’s Foreign Ministry called the alleged plan a human trafficking ring. It said Cubans, both in Russia and on the island, had been recruited to fight in Russia’s war against Ukraine.
And South Americans are being recruited by Ukraine to fight Russia.

Russia captures Colombian mercenary fighting on behalf of Ukraine.
Good.
If at this point anybody willingly accepts any job in muscovy, they deserve everything that will happen to them.
Too stupid to know what they’re going to face or really desperate to leave Cuba?
Cuba probably keeps them in the dark about what’s happening.
If it’s like their recruitment in India, it’s promises of big bonuses and “no, you won’t be fighting, you’ll be driving a truck in Kursk” or whatever.
Spoiler: they’ll be sent to fight on the front line and killed before they get that pay.
