A union of professional soldiers whose long-time president, a critic of Minister Vulin, was twice dismissed from the army; the Administrative Court annulled the first dismissal in 2023, and the union's criminal complaint against Vulin has had no known outcome. He was removed as president in 2024 while in detention, and in 2025 an indictment against him and nine other members of the union's leadership for embezzlement and money laundering took effect, which he calls a staged political trial.
