M15 Halftracks US Army

This is a Filament Fighters M15 37mm anti-aircraft halftrack with two .50 caliber machine guns in 3D printed resin.
 

This is a Roco Minitank M3 halftrack that has been converted to an M15 special 40mm anti-aircraft carrier.

I have four of the M15 specials that a friend of mine made a few decades ago.

Recently I have been upgrading my WWII US Army collection, in this case painting these vehicles.

These have the Airfix 40mm Bofors gun in the back, which even though it is 1/76th scale, it looks pretty good.

The M15 special was built in the Pacific and was used late war in the Philippines.  Only a few of these were built.  The M15 with 37mm gun was used in North Africa and most places US Army troops operated with air defense.

The US Army used AA halftracks in platoons of four guns, in companies of 16 guns.  They often task organized halftracks to mix the platoons of a company.  So rather than four companies of M16 halftracks with four .50 caliber machine guns, you might have two M16 platoons and two M15 platoons in a single company.  Figures here are old Airfix USMC figures for WWII in 1/76th scale.
