Colonel Tobin's private army is on the march... against enemies plotting to overthrow a South American government! BRAZIL ERUPTS... A country that finds itself caught up in the throes of a bloody revolution. The regular army cannot cope with the well-armed outlaws, guerrillas, and native tribes with poisoned arrows of this fanatical force. And so the word goes out: "Get Colonel Tobin!" - and his hand-picked, hand-trained collection of the hardest, strongest, most efficient mercenary fighters in the world. Men who live, work, fight, drink, and love like the devil himself, an odd band of angels who fight for their own reasons...and together are the best damn bunch since the dirty dozen! The only men on Earth who can stop a revolution...or start one, if necessary.
