MS-13 was formed back in the early 80's when salvadorean refugees fled their country to the US after living a brutual civil war. The salvadorean immigrants had no respect from the Latin gangs from the streets of los Angeles, so they made the MS-13 to help shelter their fellow Salvadoreans. With war combat experience, they used their war skills on the streets making them very deadly.
