Deep in the Arizona desert, U.S. Army developers have built a tank the likes of which the world has never known, dubbed the "Tommy Gun." But in a carefully orchestrated attack, Iranian terrorists have captured all the Tommy prototypes and hidden them somewhere in Mexico-along with the project leader, the only one who can activate the tanks. Now, CIA officer Luke Dodd and a team of Green Berets must infiltrate the Iranians' stronghold and take back the ultimate armored weapon.
