Maybe this post is useless and I’m dumb but isn’t fcs module supposed to disable the gun fire?
I’m not certain but i think that got turned off for MBT’s and light tanks with larger canons as not all MBT’s or light tanks with large canons have that module yet (or something like that). It should still disable firing for other vehicles like light tanks with autocannons, spaa, etc.
Not feature complete, it doesn’t hold a function for any MBTs that have it, but all other vehicles does.
