Enemy strength through War Path and Operations

[Mania]

Hello,
does anyone know, if casualities at the enemy are reflected in War Path or Operations? Does it matter to "grind" the enemy to death and ignore some zones in one phase to make it easier in the following phases?
Even in one phase/match are the enemy reinforcements finite or not?

Based on my experience playing warpath so far on master, it definitely feels like the enemies has finite units.

I remember being assaulted by a few veteran 3 Leopard 2s in a meeting engagement and was having a tough time with them as I don't really have that many good Anti tanks and my tanks simply weren't up to par. After going through great effort to destroy them a couple of times, I noticed that the AI at some point just stopped sending them out. I also noticed after several wipes, the enemy also seemed to wind down, not sending as much as they should to contest the points.

Same thing goes for artillery. Wipe them once or twice and the AI at some point can't call em in anymore.

That being said, I wouldn't recommend grinding the enemies. They seem to have enough to last for the phase/stage. I am also not sure if loses in one stage affects another.

I don't know if it's actually the case, but it does seem like the enemy gets diminished after taking substantial casualties. However, I think they get more reinforcements per phase in certain mission types, especially when the player is defending.

I'm playing my first Warpath campaign and almost immediately ran into a still wall of Russian resistance in my attack posture. When I play again I will be fighting on the same map for the 4th time. Anecdotally, with huge casualties the Russians are seemingly being worn down and I am making progress in this meat grinder. Very tough situation given the starting position I have and the objectives needed. So given my limited experience with Warpath it does seem the Russians are being degraded.
