Just bought the game, I've watched some guides, what should I start out with?

I've seen stuff about community servers. And about how people tend to talk quite a bit and I should just ask for help. Does this strategy still hold up? As In, do people talk much in your games? That's part of the reason I got it (if they don't, there's always the 2 hour steam refund) I'm attracted by the team aspect in actually doing something cool with other people and hearing their voices to strategize.

What should I look forward to? How do I approach playing for the first time? My experience is naught with milsims, this is tm first. I've played a ton of Battlefield 1 but kinda got sick of the high ttk and the fact people are idiots and nobody talks or operates together
