Stormtroopers of Death (also known as S.O.D.) were an American crossover thrash band formed in New York City in 1985. They are credited as being among the first bands to fuse hardcore punk with thrash metal into a style sometimes referred to as crossover thrash. The band is also known for reuniting Anthrax members Scott Ian (guitars) and Charlie Benante (drums) with their former bassist Dan Lilker. The song "Milano Mosh" from their 1985 debut album, Speak English or Die, was the Headbanger's Ball intro anthem for many years.

The band were the source of some controversy due to the deliberately racist and misogynist lyrics. Bassist Dan Lilker stated: "The lyrics were never intended to be serious, just to piss people off." The band had several periods of inactivity following their formation in 1985. According to singer Billy Milano, the 24-song extended play of live and unreleased material called Rise of the Infidels, released in August 2007 on Megaforce Records, "will finally be the last of S.O.D.," laying to rest rumors of another reunion.
