DUSTER: HAVE GUNS WILL TRAVEL 💥💥💥💥💥💥💥The Viet Cong called them “Fire Dragons,” because their high volume of fire and tracer ammunition gave the appearance of a dragon’s breath. Their U.S. Army crews called them “Dusters,” due to the large clouds of dust they created as they sped across the dirt roads of Vietnam.
The M42 was a 1950s continuation of the U.S. Army’s World War II era concept for a highly mobile, rapid firing anti-aircraft artillery system designed to protect maneuver forces from low-level air attack. The precursor to the M42 was the M19 Gun Motor Carriage, which was produced in 1944. The M19 was based on the M24 Chaffee light tank chassis and was equipped with twin 40mm Swedish Bofors anti-aircraft guns mounted in a power driven open-topped turret or rotating shield.

U.S. Naval armaments of World War II, Part 6: 20 mm/70 (0.79 in) Oerlikon Marks 1-4
One of the most successful automatic cannon designs of the 20th century, the Oerlikon would see service, with some design variation, with all of the major powers of World War II. The weapon could be found in land, air, and sea based configurations as well. It even continues to serve in some countries to this day, as well as receiving The U.S. navy would receive its first operational Oerlikon in the form of the Mark 1 being approved in 1940, though only around 400 would be produced by December 7th, 1941. This small number, even if produced in a “peace time” setting, was in all likelihood mostly due to the large number of man-hours necessary to build each Mark 1 design. To counter this problem the design would be continually simplified to ease production, while also adding in additional improvements. This would take the approximate man-hours down from a few hundred in 1941 to less than one-hundred by 1944. The first improvement, and the model which would act as the first heavily produced variation would be the Mark 2 which featured two locking slots and cooling ribs. This model also removed the semi-auto capability of the Mark 1, which would be of questionable value against aircraft anyway. The following Mark 3 removed the second locking slot, and some of the cooling ribs to aid in simplicity. The Mark 4 would be the most common in U.S. service
e, and included a redesign for use specifically with the Imperial system of measurement. Finally the Mark 4 Mod 4 design would add a fluted barrel which overcame the need for greased ammunition necessary on former models to be able to function properly. In combat these weapons proved far more effective than their 0.50” predecessors, and quickly replaced them. During the last years of the war it was found that even the 20 mm round of the oerlikon was incapable of downing a “determined” enemy fast enough before they could engage their intended target, and such was the case when dealing with Japanese Kamikaze aircraft. - to be continued in the comments!->

U.S. Naval Armaments of World War II, Part 4: 0.50"/90 (12.7 mm) M2 Browning Machine Gun
Perhaps one of the most famous weapons of all time, the M2 continues to see service in the U.S. military today, albeit with some modification. In U.S. Naval service of early World War II, it would be used in both the more iconic air cooled variation for use on smaller ships, and the heavier water cooled variation as shown in the above pictures. It was found out quickly however that even such a large gun was not enough to seriously hinder or destroy enemy planes in a reasonable amount of time (a problem also noted in the weapon's use on aircraft themselves), and as such replacement by the 20 mm Oerlikon and/or the 40 mm Bofors would be sought in most cases, though lighter boats did still continue to equip them. The air cooled versions would be of the M2HB (Heavy Barreled) variety which had been developed to allow for sustainable fire without the need for a bulky water jacket.
The weapon itself was first designed out of the 1918 requirement for an heavy machine gun for anti-aircraft use. The actual gun wouldn't reach its first production until 1921, years after the war it had been meant for had ended. However this was far from the end for the weapon itself, and the creation of several variations would be developed, along with the recieval of the M2 designation in the 1930's. Mountings for air, sea, and land use would be created before World War II began, and all three environments would see its use. While not as commonplace in U.S. Naval service where ships themselves were concerned, the weapon was the primary armament of most U.S. carrier based aircraft, or most U.S. aircraft for that matter. Finally, the weapon would continue to be employed far after WWII itself had ended, and into the modern age. It would find use in several countries, and in an increasing variety of modifications and roles.
