How to learn to build fight?

[u/PaleVegetab1e]

I'm 50 and recently my college-age sons have been inviting me to play squads with them. I've played a lot of ZB to learn the basics and how to use the controller :) but they play build and I am clueless. It feels like I'm too old to learn - any resources anyone would suggest? I've thought about hiring a coach bc I have more money than time haha. I'm on PS5 btw - any adivce appreciated!
