There are several types of Marches boosters, but beware that if you activate several at the same time only the same type can be used! If you start a different type the previous booster is canceled.

These boosters must be activated BEFORE you start any marching.

Note: This only raises the troops you can send in one march - it will not magically give you more troops.
