One at a time?
If you look in the tech files, you will see one pattern (by category). If you look at event files, you will see another pattern (by country). Unit IDs are by country (type) and then sequential numbering (ID) in the INC files. For units build in-game, type 4712 is used IIRC.
As long as you don't have duplicate IDs you'll be fine...
