This is fantastic work already.
Like other people have said, can't wait for loadouts and the Brits/French to be playable. The massive waves of guys pouring into trenches and over shell craters is so immersive, and the battle map looks like a real war plan.
But maybe add a button to "holster" your weapon and hold it against your chest like the bots do while marching. It would really help the immersion. To add onto that, could we have the option to have the same walking speed as them so I can walk in file?
