In the dark days of WWII, a special unit was commissioned by Lieutenant James Dunmore, an intelligence officer on General George Patton's staff. Made up of tough volunteers, the unit had only one purpose-to hit first, his hard, and kill without hesitation. This band of elite warriors would become known as the Mohawkers-and the last thing the enemy would see would be Recon Force Thunderbolt.

Two days before the allied invasions of Sicily, Lt. John "Red" Parnell and this Blue Team are put ashore for a high-risk mission-to find and rescue powerful Mafia capo who can aid the allies in taking the island. But a bloody war erupts between Mob strongmen and Blue Team is sucked into it, fighting against bloodthirsty Mafiosi armed to the teeth by a brutal German Waffen-SS officer, Captain Karl Keppler.

Obsessed by his hatred for Blue Team and their partisan guides, Keppler grimly continues hunting them throughout the invasion of Salerno, through the bloody guerrilla fighting on the Volturno River and the great Liri Valley, to the final, deadliest event of the Italian campaign, the assault on Monte Cassino.
