I am Looking for Advice on Joining Operations and Improving Skills.

Hello everyone:)

I am new to the 49th community and want to learn more about arma 3 operations and how I may get engaged. Could you please tell me how to participate forthcoming events or missions? I would like to hear some advice for strengthening my tactical skills in the game since I want to be well-prepared for team based scenarios.
Any suggestions for mods or resources that are crucial for new participants in our group would be much appreciated:)
