for those who say 3 tanks over complicate things... why? Because u do it like this? Yeah we did it with 2 tanks the first week as well, and it was messy as hell... If we had known the things we had today, we had went with 3 tanks as well and one shot instead back then. It is not that difficult on normal, but still, why would anyone suggest making it harder for them?
Stick with your 3 tank strategy, just go up the hill instead of into the hut, then there is so much more space and things wont go messy for you
