The heavy weapons section looks promising. So far, the only correct M1919A4 light machinegun team in plastic has been the Conte offering with the the TSSD M1917 gunner being second (but these guns were at battalion level) The old Airfix M1919A6 gunner being a far third. The US Army used the M1919-series as the basic infantry machine gun. The heavy weapons companies provided the M1917A1 .30 cal water-cooled guns and any .50s usually came from battalion also.
