Your first command could be:

Vanguard-1 capture the Nexus. Scout-1 scout the east relay. Striker-1 attack the nearest enemy. Sentinel-1 defend E7.

The Training AI is a deterministic keyword interpreter: name units (Scout-1, Vanguard-2…), give an action (scout, capture, attack, defend, repair, hold, move, deploy) and a target (a sector like E4, the Nexus, the west/east relay, the nearest enemy). Live models like OpenAI, Anthropic, xAI and Gemini understand far looser strategy.
