How do you train your troops?

Troops are trained in 3 separate buildings, one for each of the troop types.

Cavalry are trained in the Stable

Footmen are trained in the Barracks

Archers are trained in the Archery Range

Tap on each building and select the Train option. You can then select the level of troops to train and the amount. This requires an amount of resources.

To increase the amount of troops you can train in one go you must build and upgrade the Encampment buildings. Research and some heroes can help with the speed and costs.
