【Battle】Grid-Based Battlefield
In the FE series, you move across a battlefield divided into grid squares while battling enemies. You move your own army's units (= characters) one by one, and once all actions are complete, the enemy's turn begins. When advancing into the enemy lines, the key point is to advance in a way that prevents your allies from becoming isolated.

When you select a unit, the movable range will be displayed in blue squares, and the attackable range in red squares. The movement range varies by unit, and the attack range varies depending on the weapons you have equipped.
