Feel free to join the 'ARMA3 S.W.A.T. GROUP' which is dedicated to this scenario.
There you can announce your 'S.W.A.T.' server(s) or hosting hours, start discussions, make suggestions for changes, find new team members or idle in the chat room and let them find you instead.

The group is handled by me and the author Roque_THE_GAMER himself.

We explain the mission updates a little bit more in depth here and we would love to hear your thoughts and suggestions about it.
