1. I advise to add "F"menu to pick up items like ARMA3,,you see many tuff in camp,,,
for exaple,you can light the fire in the evening and make a coffee before margin.
2. I see the blue smoke,,,my eyes mistakes? background is too blue?,,maybe HDR could solve
3. I advise ctrl twice to toggle lie down position,,,as you can decrease the arteliry damage,,,if you know scourage of war:gettyburg youcan find it though its a RTS game
youcan lie down on the stone wall if ground is flat enough,it's more close to realism
4. maybe a in game profile is needed to limit change roles too often and higher units could attached on some condition to make them act like they were real elite uint.
5.that's all you can taken to change some detail of the game.
