Soldiers need to use the Anti-tank weapons by themselves, you should also be able to order a soldier to place a claymore of throw a nade in a certain area. Maybe some vehicles a la Operation Flashpoint would be nice.
Damn... I was hoping there was something more easy. Is there a mod with Canadian soldier skins? I have Canadian Operatives 1.0 but it has some major bugs and some of the skins I don't like.
