First up is the top-secret scanning device that will stop terrorist attempts to smuggle liquid bombs and guns on to passenger jets. Next, Mack takes command of the newest rapid-fire naval gun as he tries to take out waterborne suicide bombers. Back on land, he wields the very latest security detail carbine when he goes head to head with the Roswell SWAT Team during an exercise to protect a VIP from assassins. Then he gets to test the newest remote-controlled weapons station for armored personnel carriers. 

FutureWeapons goes big on guns starting with the rapid-fire cannon that's fast becoming a huge hit with the U.S. armed forces. Next up, Mack takes a helicopter ride where he unleashes a firestorm with the lightweight Dillon Aero Gatling gun. On an Arizona firing range, he tests a new multi-caliber combat weapon that's lighter and tougher than any other weapon in its class. In the finale, Mack checks out a new breed of personal defense weapons that have the stopping power -- and amazingly, the accuracy -- of much bigger weapons.
