I didn't want to necro it.
There was an old mod that gave certain large units from vanilla supcom modular weapons. It's in the old archived vault and is called "Modular Damage".

I have tested it and it works with FAF. It just needs some ironing out and some TLC for the Seraphim units (which came out after the mod stopped being developed). I haven't been able to add more modules to other units myself yet, but until I do I invite others to mess with it as well (or just drool over it).
The reason I brought this up is because I want to hear what other people think about making units in supcom FAF modular so that certain parts of them can be disabled.
