Long campaign

[Steph]

So... The long campaign is here only to play a few years... When why allow upgrading units to newly released models?
In WWII, we can have a fun long campaign with Germany for instance, playing the whole war on several theaters.
I'd like to do the same with MBT, start in Korea, then move to Vietnam, then anywhere else, but keep the same core troops. Of course it's not the same generation, but it could be the same training, standards, etc.
And by the way, when you take loss and repair the unit, you do get new generation.

I'm surprised to see that apparently I'm the only one to try that. Was it so unexpected to play such kind of campaign?
