Although designed to combat massed Soviet armored formations, the Patton tank was an invaluable weapon for infantry support and defending firebases

Based on the Lockheed L-1049 Super Constellation, the EC-121 Warning Star carried the long-range and height-finding radars required to provide coverage and warning to U.S. aircraft operating over North Vietnam

The USS Grayback, whose missions during and after the Vietnam War remain classified, was the only U.S. Navy submarine capable of covertly delivering Marines or Special Forces to an enemy shore

During the Vietnam War, the M-3 submachine gun, commonly called the Grease Gun, was a favorite because it provided instant close-range firepower, was tolerant of the field environment and was easy to maintain

The RPG-7 is a recoilless muzzle-loaded, shoulder-fired antitank weapon that fires a fin-stabilized rocket shaped like a warhead. During the Vietnam War, it was carried by every infantry squad in the People's Army of Vietnam (PAVN)
