Ultimate Strategies Mod can easily be combined with any mod out there. All you need from it is the Formations.txt and DefaultStrategies.txt files in the Data folder. As it has nearly all the formations from mods that I could find, it won't hurt to overwrite the formations files in those mods. I don't think many (if any) other mods make changes to DefaultStrategies.txt. I could be wrong, but I haven't seen mods with differences in that file.
FQM Standard can be used to generate maps, and then you can load them in most other mods. For info on how to combine the mod with other mods, look in the Help folder for FQM STD 1.18. When I release FQM DLX 2.02, it will also have this info in it. Or, you can go to the FQM web site, which is linked from my home page, at
*my web site*. Combining FQM Deluxe with other mods gets a little trickier, but can be done if you follow the instructions.
Combining tech/comp mods together gets really tricky, and I would not recommend it until you learn more about modding SE4. You can visit the SE4 Modding 101 Tutorial (linked in my sig, or from my web site I linked to earlier), which will introduce you to the wonderful world of making mods for SE4.
