Research effect
The upgrade requires the Treaty of Westphalia Home City Card and takes 15 seconds to research. It affects eligible Infantry under the German roster and rules. The higher price changes future production; the speed gain helps troops reposition, pursue or withdraw but does not increase their damage or health.

Cost and prerequisites
Research when Infantry mobility will matter repeatedly and the economy can sustain the price increase through a full production queue. Faster foot troops can reach an objective or support a flank, but each replacement costs more. Check which Infantry types are affected in the active version and delay the research if immediate army numbers matter more.
