Brits/Canadians cos I am a Brit (though definitely NOT a nationalist) and they are not in the slightest boring . They have Crocodiles, Fireflies, Wasps, Typhoons and Kangaroos (lets hope they also get the AVRE soon ). They also had the most interesting Normandy battles. THANKYOU, THANKYOU, THANKYOU, Bigtime, for including the Brits in CM1 and not going the way of Panzer Elite and Across the Rhine with their purely US/German fictionally-rigged battles...
I also like to play non-SS German units as a personal preference.
