The halftrack-mounted 75mm gun was not issued to regiments until near the end of the Guadalcanal campaign. Towed 75m M1897A2 field guns were used instead.
While the TO&E prescribed 20mm guns, battalion AT platoons were actually armed with obsolete 37mm M1916 infantry "AT" guns due to the priority of fitting available 20mm guns aboard ships. The M1916s, used as training weapons, were replaced by 37mm M3A1 AT guns before the units were committed to combat. M1 rifles and M1 carbines were in limited supply until fully fielded within the FMF in late 1943. M1903-series rifles were issued in their place. Limited numbers of flamethrowers were issued in late 1942. |
