So does the AI just magically cheat??? Had a scout inside an enemy AI base(moderate difficulty) and all of a sudden 16 units from both their barracks and archery spawned in the same frame...???

So I brought my scout down to the enemy base and had him standing between the enemy barracks and archery.

All of a sudden the enemy Archery spawns 7 units and the barracks spawns 9 units all in one single frame.

Were they somehow garrisoned? I tried to garrison my units inside the barracks but it did not work.

What am I missing here?

My Green unit is selected. In one single frame all of those enemy units popped out at once...

So does the computer just have the ability to spawn that many units in one go or were they somehow garrisoned??
