This project is a HoI 4-inspired combat sim made in Python3. I'd been trying to make a battle sim for a while, and thought this was a good start, so I posted it here.
Download the project files. In main.py, edit the attack_units/defender_units lists to change which units appear in battle. Run main.py to start the combat sim.
This project has several doc files explaining sim mechanics below:
