The Grupo de Ações Táticas Especiais (Portuguese for Special Tactical Actions Group), mostly known by its acronym GATE, is a hostage rescue, bomb disposal and Counter-terrorism unit of the Military Police of São Paulo State in Brazil.

GATE was created following a case in 18 February 1987, when former ITA students held a three-month old baby, Tabata, hostage for eight hours in Mogi das Cruzes.

[3] At around 6 p.m., the suspects were killed after a shootout and Tabata was rescued, sustaining knife wounds in the process.

The case convinced the Military Police of the need to create a specially trained team for hostage rescue operations.

GATE modeled its operational performance after American police SWAT (Special Weapons And Tactics) groups.
