Military Commander
Military Commanders are the veterans who lead your armies into battle. They get defence and attack bonuses. These are obtained based on the percentage of troops killed. If I go into battle with an opposing force of 1 soldier And I kill it; I will gain the highest amount of attack percentage which is 10%. You can only gain either 5% or 10%, In any one battle. You can only get a maximum of 100% attack and 100% defence for each Commander. The higher these are The more effective your troops will be. The higher attack means, you will kill more troops. Higher defence means You will not loose many troops. So it's good to get these bonuses up at the start of the game, by constantly attacking people.
