Use your units as map reinforcements

Work on a copy of a valid map

The included XML is a triggers object-layer fragment without terrain or map dimensions, copy a working TMX map and merge the object into its existing triggers group

Create the reinforcement object

unitAdd creates units, team:0 chooses the receiving team, delay:10s adds a delay and spawnUnits lists internal names with counts, choose a reachable location

Check team and mod dependencies

Enable Field Academy when running the map and ensure team 0 exists, valid XML alone does not guarantee available units or teams, first confirm that all units can be spawned in the sandbox

Verify with messages and counts

Observe the message after ten seconds and count two recon vehicles plus one twin tank, if the message appears but units do not, inspect names and placement, if no message appears, inspect the layer and trigger conditions
