There were some "civilian" single shot (single barrel) shotguns in South Vietnam...probably brought over by some early US servicemen. In the meantime, the standard pump 12 gauge US Military shotgun has always been the Winchester Model 1897 pump shotgun. This model is easily identified as it has an exposed hammer at the receiver end; and companies don't make exposed hammers on rifles and shotguns anymore (unless they are replicas of something). The Remington pump transitioned thru the inventory during the war, and shortly after the war, came the Mossberg.
About a dozen or so !2 Gauge pump shotguns were authorized for US Army infantry companies during the Viet War. Very seldom were they issued out, but when they were usually a patrol might have a shotgun man walking point or second in line. Possibly its lack of much use was due to the M79 (later M203 over & under) grenade launcher's capabilty to shoot buck-shot (called cannister during the war) in addition to the weapon's normal 40mm grenade.
The '79 was also referred to as the "Thumper" or "blooper" as that's what is sounded like went it went off. Every dismounted patrol had a grenadier (thumper man). And some GIs weren't that impressed with the weapon; neither its can round (can short for cannister) nor its H-E (High Explosive) round. The H-E shell (H-E grenade) did not compare to the devastating power of the hand thrown frag (grenade). But it was the army's latest toy, so they wanted to use it.
During the Vietnam War, all combatants (including North Vietnam) used draftees except for the New Zealanders, they sent volunteers to South Vietnam.

NO!
Napalm bombs were used in the Vietnam War and killed a lot of people.
Rifles, shotguns and handguns differ mostly on the type of cartridge used.
Actually, some of the first firearms used in combat could be classified as shotguns, although they were rather large and mounted on the castle wall. Some Southern cavalry carried short-barreled shotguns, and US troops used "trench guns" in both world wars, Korea, Vietnam and both Gulf Wars. It is a common weapon used by security forces on ships, as the damage to the ship itself is not going to be great compared to what it will do to an intruder.
