SOD meaning in Military and Defence ?

Stormtroopers of Death (abbreviated to S.O.D.) was 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. Their instrumental song "March of the SOD" from their 1985 debut album, Speak English or Die, was the Headbangers Ball intro anthem for many years. Another song from the same album, "Chromatic Death", was also used during the show as a segue between ads and videos.

The band were the source of some controversy due to their deliberately offensive lyrics. Scott Ian described the songs on Speak English Or Die as "ridiculous" and "just a big inside joke", adding: "Some people thought we were racist, and those people are stupid." 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.
