Gunboat: an agile arsenal that can turn 29 knots in the swat of a mosquito. Eight tons of firepower crammed into a 30 ft. hull. For decades, the U. S. Navy has deployed the river patrol boat (PBR) for a most hostile and claustrophobic type of war: riverine combat. Now you've been drafted.
The Colombian drug cartel. Loyal troops of a deposed Panamanian dictator. Renegade Viet Cong. They're on the river — waiting — around any river bend. Bullets rip through the thick jungle air as you maneuver your Gunboat through over 20 missions in hell. They swear the river will run red with your blood. But you've got other orders.
