# Movement

**Moving Units**

To move units between friendly countries, first select the source country during the [Attack](/border-clash/game-mechanics/how-to-play/turn-phases.md) phase. Then, in the context menu, select *"Move"* *(Hotkey: Shift)*. 

Now, select the friendly target country and the number of units you want to move. One unit always needs to stay behind to defend the country.<br>

**Visibility**

Unit movements, like [attacks](/border-clash/combat/declaring-attacks.md), are not visible to your opponents until the start of the [Battle phase](/border-clash/game-mechanics/how-to-play/turn-phases.md).<br>

**Outsmart Opponents**

Unit movements will be executed before resolving attacks (see [Combat](/border-clash/units.md)[ system](/border-clash/units.md)). This can be used strategically to reinforce a country's defense when expecting an attack from an opponent.<br>
