With this SMS Function, is it done with one module per munition type? The scenario that I'm in here is that I help run a publicly facing server which is used for recruitment. In order to help mitigate people carpet bombing, dropping mine clusters, and to over all try and reduce asshattery, I've selected 75 ish of your munitions from the FIW_AWS list to whitelist. We utilized ammunition vehicles and ACE Pylons in game to modify the pylon settings for both FIR F18's and RHS helicopters. Will I need to place down one of these SMS modules per whitelisted munition? Is there another way to try and mass whitelist/blacklist munitions?
