Hey lamenofking.

You should look at the branches individually and then add them all up. A branch consists of the authority tree with Ghenghis at the root and the lowest level soldier at the bottom.

If each set of branches is the same as every other branch at that level in the tree then you can use the multiplication rule and the total number of branches will be found by multiplying the numbers of nodes at each branch. If this is not the case, then you will have to add up each branch individually and simplify where-ever possible if you can.
