# Unit Management ## Unit Management
Modifying Status You can click on a unit's status for a dropdown menu to quickly modify it.
Units can also select one of the status buttons in the header:
Modifying Unit Information Click on any active unit and select "Edit Unit" to change their identifier information.
Units with the edit identifier permission can also click on their unit number in the header to open the identifier editor:
Unit Groups Unit groups are a way to combine two units together, typically when they're in the save vehicle or apparatus. To add a unit to a group, simply select the unit and select **Add to Group > New Group** or an existing group. Or, drag-and-drop a unit to an existing group to attach.
Persistent Unit Groups Unit groups can be configured as **persistent**, meaning they remain visible even when no units are assigned. Persistent groups are set up in the Department Editor under **Admin → Customization → Departments**. These groups can optionally enforce a maximum number of units that may be attached.
Once configured, persistent groups can be dragged into the Call Editor or onto an existing dispatch call to attach them.
Units can self-attach to these groups by clicking on their unit number to open the identifier editor **→ Persistent Group**
Automatic Unit Status Dispatchers can also customize what to automatically set unit statuses to after specific actions. Select the [**Automations**](/cad/tutorials/dispatching/automations.md) button in the call editor to enable status changes on call attachment, detachment, and closure.
