I noticed while playing beta of div 2 , there are 3 of the old style div tech boxes from d iv 1 either sunk into the ground or facing the wrong way which doesn't allow you to open them ,, the sunk 1 is in the room at the back of the underground that you access from the triangle area sorry cant remember full name , the other 2 are in dz 1 of which is next to the bridge you go to in the story mission to scan the layout ,, the other i found is at the top left of thdz down a ramp with a truck next it
