Is there a way to increase the rate of how much reserve you generate? As Iraq, it does take forever.
You can raise your military salaries but dont expect a big boost. Its kinda based on your population, type of government and probally a few other factors.
If your using garrisons, you can lower the amount of those in your cities and it will go to your reserve pool. You can also deactivate facilities to gather the manpower and/or reserve units.
