Rally Points
After troops have been created they will by default all assemble just  outside the Barracks, Military Academy or Siege Camp. To change  the default place where troops assemble, select the Barracks, Military  Academy or Siege Camp, right click on the Rally Point button, then  right click on the map where you want them to assemble.
To place a rally point individually for each troop type, right click on the  troop icon, then right click on the map.
