In the training menu you can enlist the help of several types of units. If exploration is your goal, select the Scout option and press the TRAIN button. If you are looking to expand your Kingdom, you'll want to train a Pioneer unit. They can start new cities and establish outposts on the fringe of civilization. If you wish to increase your military might, you will find Milita and Spearmen units available. Building special improvements will unlock more units to train. Every unit trained uses a LOGISTICS point.
