# Disband units fraction effect by Yard1

Disbands a percentage of the army (just the army), returning equipment and manpower to the stockpile. Useful to eg. force an AI to reduce the size of their army after a war.

`SOL` must be replaced with a tag from your mod that never exists (a utility tag).

Please note that the size is rounded up to divisions. For example, if you have 4 divisions and want to disband 1% of the army, then one division will be disbanded. This is unavoidable. Which divisions are disbanded is also completely random.

Usage example:

    # disband 10% of the army of the current tag
    set_variable = { disband_fraction = 0.1 }
    disband_units_fraction = yes
    clear_variable = disband_fraction

# Disband units fraction effect by Yard1
# remove disband_fraction land units, keeping manpower and equipment
# expects disband_fraction variable to be set
