Yeah, it's pretty massive in comparison to other DLCs and/or stock campaigns and it gives you a lot of options at tactical mode, so you can for example while defending on one side of the map attack with notable forces on the other one.
The only thing which gives player a headache are supplies, maybe because menu doesn't fit Shilovo OOB, It's really hard to adjust supplies every new turn, cause there are lot of units under player's command.
Anyway, every DLC bring something new and campaigns are amazing
