This mod is designed for those who feel there just aren't enough units fighting during a war in Civilization IV. The solution: Change the cost of the units so they're cheaper. Veterans of Civilization III will notice that the new unit costs are based on the CivIII costs, but modified slightly where necessary for balance. All units except the Carrier, Stealth Bomber, and ICBM cost less than they previously did.
New Building Costs:
Barracks: 40 shields (from 60)
All others have not changed.
New Unit Costs:
Instructions: Download the .zip file, unzip the contents (folder should be named "More Military Units", and move the "More Military Units" folder with all its contents to C:\Program Files\Firaxis Games\Civilization IV\Mods\, or wherever you installed Civilization IV.
Any feedback is welcome. I haven't tested this extensively, just made sure it works, so despite my logic when I created this there may be some balance of power issues. Here are some things I'm almost certain will happen, and a few others that will be different from vanilla CivIV.
