Enhanced Movement is helpful when doing missions.

I love building bases almost as much as playing the game; you can get pretty creative with vector building. I thought Vector Building was now part of Exile, but I may be wrong.
Enjoy playing on your server. It's been a long time since I've played ARMA3, so bare with me.
I used to setup and program ARMA3 servers.
