I haven't been able to sort out Respawn Loadouts to work the way I wanted, so I've given up on that. Currently, loadouts are determined at the beginning of the mission, using the loadouts I gave each unit in the editor.

The goal was to allow players to use the respawn menu to chose from several loadouts that were appropriate for their job, as expected of the unit they selected before entering the mission. I tried limiting options by faction and by variable name, but neither worked properly.

I may have to come back to this from a different direction later on. Limiting the number of loadouts allowed at a time.
