Just got ARMA 3 on sale on steam, where do I start?

[Cryyo]

There are a lot of different things to do in this game, but I am an amateur and know nothing about it. Where should I start training? I don't want to just jump into some multiplayer mode and ruin a round for everyone, as I know the game is considered pretty hardcore. What are your suggestions?

Learn the controls for the infantry, and set up the controls for piloting, you should be able to do the training for those in the options menu if i recall correctly then you can jump into multiplayer mode.
