Cantonal Infantry:
Because the cantons are financing the training and equiping of these units, they are cheaper than regular Swiss infantry. However, because they are under command of the Cantons, they are less prepared to go on offensive campaigns, and have slow campaign movement speeds as a result.
Cantonal Battery:
Additionally, the Swiss have "Swiss Foot" as their normal infantry, same stats as France's, but unlimited in quantity and can be recruited anywhere.
