# Pirin :
Everything should be loaded on the server specifically to avoid that kind of confusion. While the server might not "need" it, it prevents you from running into this kind of thing later and not loading something you need because you'd gotten used to not loading mods.
I am no server admin and am not running an Arma server at all and have no experience with it the past year (before I did), but I disagree with the above. It servers no purpose to install those addons, they are unneeded and only take up space. So, why would you do unnecassary things? I fully understand things should be kept simple but adding every addon you allow to the server as well without there being a need for it does not sound like the right administrating if you ask me.
Only install addons which need to be installed for your mission or need to run on the server as well since they change something in the game like AI like the Zeus AI mod, or ACE as it changes the game totally. Soundmods, replacement packs etc have no purpose to be installed on the server as well as it does not influence the default gameplay.
If a serveradmin disagrees with me I happily stand corrected, but this is my view of it
