Pictured above is the Brazilian boxed Robo-Metralhadora that was released as part of the Comandos em Ação toyline. It was released as part of the second Comandos em Ação series in 1986 by Estrela Toys. The toy was released in the United States as Machine Gun PAC/RAT.
Robo-Metralhadora translates roughly into "Robot Machine Gun". Note that the box art has been changed to include Comandos em Ação logos. The toy itself is the same as the U.S. version, except that it has an Estrela Toys stamp on it and the G.I.Joe decals have been replaced with Comandos em Ação decals.
