3 - Rise Of Empires Ice And Fire Gameplay: Military Tips
Train your troops constantly
You would eventually need a large army or two - and in order to accomplish that, you would have to train, collect and train more as frequently as possible. Focus on training troops early would be tremendously helpful later.
Troop composition matters - it is best that you have your infantry first, cavalry second and archers at the back. Leave archers out if you are going to gather resources with your troops.
