Desaparecidos en Ucrania

Mateus Henrique Tavares Teixeira Lemos, a Brazilian mercenary, arrived in Ukraine in April 2025 and joined the GUR Advanced Company, a unit composed mostly of Brazilians. He survived an Iskander missile strike on a training base in Kirovohrad in late July but lost many friends. He has not yet been on missions and is suspected to be an instructor. The post warns of danger from his commander, Leanderson Paulino, who is allegedly selling information to Russia.
