WarDollars

All the actions or almost give WarDollars (W$), doughs, money.
the durse is common to all the section: each action carried out by a unit of the section brings back money to its section.

The player/section/commander manages an account of WarDollars which allows him :

Tobuy new units;
To ask for a leave;
To make a gift of Wardollars or a unit to a allied section if its commander is visible by the commander of the donor.

It is also possible, when the account is low in WarDollars, to ask some another player of its camp, subject that the two commanders are visible one by the other.

In our case, I have 105 W$. So I can (after having clicked on the link "Info+":

To on leave (20 W$ per unit);
To make gift of W$ or units to another player (if the commanders see themselves).

To buy new units it is enough to click on "Buying". If the section is complete (units 4/4) it is possible to desert a unit to make place. At the beginning all the units are not accessible. To buy it, it is necessary that the section have the sufficient level. For example it is necessary to reach the level 40 to be able to use a fortress.
