Russia and Sweden extra line units

[ScholasticusMusicus]

Quick question about Russia and Sweden rosters. Both have the standard "line infantry" from vanilla. However, they also have an extra "regiment of foot" that also looks like standard infantry. Why the two standard line infantry units?

In Russia's case the "regiment of foot" is slightly more expensive and slightly better.

In Sweden's case the "regiment of foot" is the same price as the "line infantry," but is significantly better. Why would anyone ever choose the standard vanilla "line infantry."

The new units for Sweden and Russia are accurate to the Great Northern War period. The standard Line Infantry I believe are more an attempt to give them a weaker cheaper option for Garrison duties and for roleplaying later in the century when the Swedish army had fallen very far from its perch.

Plus, the newer units in campaigns are only recruitable in the home provinces. So outside of Sweden for example you'll only be able to recruit the worse Line Infantry.
