In contrast, the term “Bratva”, meaning “brotherhood,” is more colloquial and is commonly used within the criminal environment to refer to fellow group members or associates. It does not denote a specific hierarchical status but rather conveys solidarity and group affiliation.

Law enforcement agencies, particularly in Russia and former Soviet states, use more technical terminology.

These terms are often employed in legal and investigative contexts to classify and prosecute criminal organizations.
