OP if you post a discord I can probably give you more training reference material. I recommend doing small unit things to increase your odds of survival. For example, I sharpened my shovel until it is like a knife to make digging easier. Dig foyers on the side of trenches that curve so you can get out of the way of grenades and drones. Place camo netting in front of your positions to stop FPVs. Things like this will save you. I personally always have cordage and carry empty sandbags and lightweight camo netting. you need it so your position can survive grenade drops, airburst artillery, and the like.
