Curious about SE: Resistance

Recently discovered this game series and saw some gameplay, and it looks quite interesting. I see too that the newer games at least have a PvP invasion mechanic. With SE: Resistance being the newest game, I consider picking it up this Christmas.

Looking for any advice/info y'all might have for a new player who's inexperienced with this kinda game. The only sniping I've ever really done in a game is Hunt: Showdown, and that has very arcade-y bullet drop. I'm hoping for something much more realistic and the game here seems to fit the bill from what I've seen
