I just finished a campaign mode game and it has some interesting twists, such as you vote for which army your side will use. For example, fighting for South Vietnam you could pick the US Army, Australian Army, or Army of the Republic of Viet Nam. That changes both character models and more importantly which weapons are equipped.
Win a round and your team votes to pick the next map. Each round represents one year of the war which affects available weapons, air support, and for the last couple years US and Australian army aren’t there any more.
My side was so bad we lost 2 years early. I’m tempted to jump right into another campaign even though it can take several hours if sticking around for the entire war.
