From my many years of playing both Arma 2 and Arma 3 servers alike I have seen from many different ways of communities trying to find ways to improve role play. By far the most successful thing I have seen put into affect was removing the ability to check names via space bar. This inter would stop people from being completely obliterated from 4k out with atgms and lock on missile systems at people would not know who they were shooting at. You may wonder well what if someone breaks a rule how is someone suppose to know who it was if you cant see their name, and there is a simple solution to that instead of a players name showing up when you space bar on them their PID will show up it is a simple enough script that I have seen implemented on many Arma 2 and Arma 3 servers. Please let me know what you guys think and if you have any questions feel free to ask.
