I'd like to see a RO Mod with Canadian and/or Australian forces involved..... both countries' troops were referred to as "Shock/Storm Troopers" in both WWI and WWII, as they would be sent in to do the jobs other allied forces failed to complete and became feared by many in the German Army.
I think it'd be pretty good having both within one Mod, as the uniforms and weapons would be almost similar, you could use the same german models and weapons with a few tweaks based on map locations and dates, modify the accents in each map, and design maps based on the battles each were involved in.
If I remember correctly, Darkest Hour has US and British soldiers playing.... but to me, it's just not a good filler for the type of game play that could exist being a Canadian or Australian Shock Troop coming at a heavily fortified German position, or vice versa. DH does have Commonwealth character models and the sort, but they're not clearly defined and still focuses mostly on the British & US.
Looking up the details on Shock Troops, the Soviets used Shock Troops in Stalingrad, so I think the above would be fitting.
One thing I came across online was the following:
1. Although few people know it, the term derives from the name Germans called Canadian Expeditionary Force soldiers during WWI ("Sturmmann"). Certain divisions of German soldiers, both in WWI and WWII, would later call themselves this name. Its meaning is exactly what you would expect--troops capable of quickly and efficiently overcoming opposing forces.
