How much does your core change over a campaign?

I usually start out with the formations I want and then upgrade along the way, but I think next time I will start out small, and then work my way up. Represent the progression from company to battalion commander and so forth.

I play just as a commander quite often progress through formations rather than ranks though. Might start in charge of foot sloggers depending on side playing few tanks if any though might have the odd TD but mainly ATGs. Then might upgrade to a mech formation with a bit of armour before switching to an armoured unit. Easier to do the other way once have some experience mind you but gives diffrent challenges. Recently started buying 2/3rds as second line units & upgrading to regulars once become elite, can be hard at start depending on side playing. Nowadays just upgrade when I need to not as soon as new gear is out & always replace the whole company not piecemeal. I often delete & rebuy so formation is correct for the time but thats just me lose your experience doing that.
Much as dont upgrade straight off if strugling might do combat trials & buy a platoon of new gear with support points in the mean time. If apprporiate will change 1/3rd or so of my infantry to ski & back for winter if short on transport.

Definitely,in the early battles it gives time to grow.

The advantage in playing the AI is it will never get more than the value of your core+support.

Not so if playing a human in a campaign however,
It's totally different as when you lose it gives the other guy more points to expand/change and repair while you may only be able to just make repairs.
Of course when winning same applies.:-)
