Tanks and artillery , heavy weapons : all available WWI
and WWII ranges.
Both sides used the French FT17 and built their own copies. The
Machine Gun version and 37mm canon version were both used (Navwar
code GWF1 and GWF2).
The Russians built a version of the Austin Putilov armored car.
Both sides used captured and bought British MKV tanks. As well as
German WWI tanks but not in large numbers.
Note on tanks : Tanks at this time were slow and many on either
side in bad condition. This was an infantry cavalry war with cavalry
much more mobile and often more effective in battle than tanks.
Guns/ Heavy weapons :
WWI and WWII machine guns French and English as well as German and
Russian would work for both sides.
Guns : it seems for artillery some favorites were German 77mm gun,
French 25mm gun and 76mm Putilov field gun.
Note on guns:
In general , many WWI guns would fit as the Russians hoarded artillery
during the war and would have captured all sorts during the civil
well. Same variety for the Polish with newer units of the "new
being equipped with more French guns. The Polish army at this point
described as a logistical nightmare with weapons and ammunition
from France, Germany, USA, Austria and Russia so a variety would
For armored trains : no idea yet . Perhaps the Navwar trains would
be good. For transport horses would be the norm especially for the
Poles (use WWI German and British colonial horses/train).
