This mod expands the roster of units that can be purchased when you adopt the Mercenary Army policy in the Commerce tree in order to make it relevant past the Medieval Era. The units now available through this policy are:
Landsknecht: Raiding Unit - same stats as in the regular game (available at Civil Servants)
Swiss Guard: Defensive Unit - strength 24, has a bonus to combat when in friendly territory and a massive defensive bonus when next to your capital (available at Metallurgy)
Foreign Legion: Offensive Unit - same stats as in the regular game (available at Replaceable Parts)
The upgrade path for these units is as follows:
Landsknecht -> Swiss Guard -> Foreign Legion -> Infantry
Note: When you upgrade to the Infantry unit, your unit gains the negative promotion "Foreign Fighters" which causes your unit to ignore the positive bonuses received from Great Generals and to gain XP at half the normal rate.
The Volunteer Army policy remains unchanged.
Installation: extract files to your mods folder (default path is Documents/My Games/Sid Meier's Civilization 5/MODS)
