Am I missing something or is it just hard coded? I want to make an upgrade to allow 2 units to be built at a time from the barracks. I looked for some kind of requirement for attached reactor and such but could find nothing. What game element (if any) allows you to build two units at once? I don't want to just disable the tech requirements, I want to be able to craft my own custom upgrade for this without using the reactor add-on.
Look at the "Nuclear Reactor - Queue Buff" behaviour.
In the Behaviour -> Modification -> Behavour section, "Queue Count" is set to 1 (+1 queue), and "Queue Size" is set to 3 (the upgrade from 5 to 8 queue slots). The behavour has the requirement "Have Attached Nuclear Reactor", and is present in all the terran buildings that use reactors.
Edit: As for actually having more than one unit training at once from the start, the Queue ability of various production structures also has a "Queue Count" setting in its stats (the one subsequently modified by the behaviour).
