So I saw in May 2022 that @MightNight created a patch for JNR 6T units which I was looking for back then and used it, it works perfectly !
Since other people asked for 6T support, I thought that giving more visibility to the patch would be welcomed :D

2 steps :
- modify the SQL mod file by replace its content with this Pastebin[pastebin.com]
Default location is : C:\Program Files (x86)\Steam\steamapps\workshop\content\289070\1665310405\ZeesStrategicResourceOverhaul.sql
- modify both LoadOrder tags in the modinfo file with a high value (20000 by default, more or less if you need it for other mods support)
Default location is : C:\Program Files (x86)\Steam\steamapps\workshop\content\289070\1665310405\ZsStrategicResourceOverhaul.modinfol

And that's it ! Should be working fine

PS : I would personnally also welcome patches for S&T: Unique Units + Everything Enabled, and Warfare Expanded additional packs (Medieval, Enlightenment & Armored Assault), if anyone is motivated to do it :p
