Hit squads are groups of individuals who are hired to carry out a mission, often involving violence or assassination. There are several synonyms for hit squads, including assassination teams, death squads, elimination units, execution squads, and tactical units. These groups are often formed by governments or organizations to carry out targeted killings or suppress dissent. The use of hit squads is controversial and often violates human rights, as they operate outside of the law and without oversight. Despite the negative connotations associated with hit squads, they continue to be used in various parts of the world as a means of achieving political or military objectives.
