American Twin 20mm AA Gun Mark 4 .stl pack – 28mm scale
$4.50
The Twin 20mm AA Gun Mark 4
The Bolt Action Mariana and Palau Campaign book introduced new units and weapons for both the American and Japanese player. On page 134 the American player is given the option of the Mark IV twin Oerlikon 20mm auto cannons. In WW 2 anti-aircraft defence was not as dominant a concern as other combatants, due in no small part in the emphasis given on achieving air superiority. However, in the pacific the nature of the warfare was different than the highly mobile war of maneuver in Europe, and rear echelon were at risk of both air attack and sudden fanatical ground assaults.
The USMC employed a unique twin 20mm cannon. The platform was unlike the pedestal mounted twin Oerlikons employed by the U.S. Navy, as the field mount needed to ensure its own stability on not rely on the mammoth weight of a warship to provide a secure mount.
Here is a good link to the employment of the guns, and a rare photo of it in the field.

The gun was normally loaded with sixty round drums, and had two gunners, one on each side of the twin mount.
This .stl pack includes the basic and pre-supported .stls for the gun, the two seated gunners and the optional gun 110mm round base. As the printed gun is a “crucifix” style mount, it would benefit from a base to ensure safe transport and storage. There is a central raised flat platform to mount the gun, either permanently or with two sides tape. The gun base has a recess for the third gun crew member’s 25mm base.
This .stl pack is only suitable for resin printing.
The gunners include the base gunner (left and right) and the same without heads, intended to secure a head from a 28mm bits box. The model shown in the photo have heads from the U.S. Army box.
