American marines in Afghanistan have a secret weapon- Metallica, Thin Lizzy and Offspring albums.

The heavy metal sounds are now being used on the frontline in Afghanistan. Marines are allegedly blasting heavy metal into villages in Marjah, hoping to subdue the Taliban... who "hate [this] music."

When rebel forces start firing on American soldiers in Marjah, an armoured vehicle with "powerful speakers" fires up the tunes, blasting rock and heavy metal so loudly that it can be heard two kilometres away. It plays for several hours.

As the military blasts Offspring's "Pretty Fly for a White Guy", children cover their ears and insurgents lay down their arms. Mixed in with the songs are messages from the Afghan government and threats to the Taliban resistance. There are no obscenities, "but we tell them they're gonna die".
