It turns out we only need 2 grenades to break all the switches in the container maze, not 3 like it says in the minimum shots fired FAQ. I'm not sure how well this is known since I haven't been able to find a single video showing how to grenade the switches in the second container, but the high up switch on the left of course needs to be grenaded, while the one on the right can be easily knifed. I figure surely someone has found this out by now, I just wanted to make a reference video since I couldn't find one. Also, everyone knows about the grenade in the final container, but I just put it in here for the sake of completeness.
