Personally I really want Poland added to the game in some way.
Either as their own nation within a France-Poland-Belgium-Netherlands tech tree (see my post on that)
OR
within the USA-UK tech tree.
In an ideal world USA and UK-Commonwealth wouldve been separated so that UK-Commonwealth could have additions like Free Polish, Greek Army, Norway etc.
For Polish in the Allies we actually dont need much. To my knowledge Free Polish soldiers used standard British battledress. All we need is POLAND written on the side (same option should be available for CANADA, AUSTRALIA, NEW ZEALAND etc.)
Ive previously suggested adding Polish and Czech names occasionally to ‘British’ soldiers in recognition of the Free Poles and Free Czechs who fought in the British armed forces.
Ive also requested Tobruk be added many times. We have an Italian Tobruk squad, it’s a very famous and important battle, would provide much needed variety for desert maps and would be an opportunity for Australian, New Zealand, Free Polish, Free Czech and British Indian soldiers to be added. (either as squads or customisation options).
As for the original post, I mean, I’m not against it entirely. I actually suggested in my FR-PO-BENE post that the faction could queue alongside USSR (Allies) in Berlin maps as Polish soldiers (I believe they were the first into Berlin?)
But ultimately I would want advice from any Polish Enlisted players. Would they be comfortable with a Polish squad in the USSR tech tree, or indeed a Polish squad in the Axis tree?
If there were Allied Polish squads could we have the above two options?
Free Polish in USA-UK tech tree should be top priority OR a France-Poland-Netherlands faction. (Poland fought from 1939-1945 after all and they are the reason most of the world went to war in 1939/40).
For pure gameplay Id be open to Polish squad in USSR, would be nice to have more variety, but yeah, up to actual Polish people to decide that I think.
