To directly answer:
```In simplest terms, is it like a giant AI ambient war with supply and strength levels?```
It is like a command center that remembers all the commands it has given out and the messages coming back from its units. It uses that information to determine what commands to send out next.
```How many AI are up in the air at one time and how many people have you tested this with online at once? ```
For the above mission, specifically, when all unit groups are at max:
20 on road units
~100 artillery units
150 some entitied statics
It should be noted that maximum unit numbers only really occur when there are no mulitplayers online. With people out their shooting stuff the numbers will be lower, but the spawn rate a bit higher.
For the above set-up specifically I've only tested with 7 multiplayers and the server ranged from 36 SPS at lowest to 50 SPS. Generally around 44 SPS.
Brojke nisu impresivne al' bitno da se nesto desava!!!
