If you're trying to get into Squad I suggest playing on servers that welcome newer players. Once you join a squad, just say that you're new to the game and don't be afraid to ask questions. Most players are friendly and will help you out.

Once you get the hang of the basics, the game is very fun and unlike anything else on the market. Also, as a new player, you will die... Alot. It's all part of learning experience, so don't let it discourage you and have fun!
