Towards the smaller base, find these crates/barrels



Stand on them and look down the center of the structure to find the can
(SNIPER RECOMMENDED)

Inside the building, find the object with a blue tarp



On the blue tarp you will find the can

At the blue base, stand towards the teleporter(preferably jump on the teleporter to see better)



look towards the trees and just beyond it, you can see the can
(SNIPER RECOMMENDED)

Go towards the side of the map with the yellow lights



you will find the can in a corner covered in rubble
