the battle part is like paper scissor stone loh
when one general pit against another, ie. one's whose troop is
melee against the other's whose troop is ranged, the ranged general
will be less effective by 25% in combat loh. 
i think it is something like turn based, u can only
use one general for each battle until the war is over
the number of losses depend on troop size, level of general and
combat roll done by yuny. so there is an uncertainty on the combat
roll!!
