This is a night mission, head into the ruins and go to the buildings at the far end for most of the crates. however be advised there are a couple'a places in the ruins where crates are stashed .......
Take out the tank for a forward respawn point, but beware, it puts you right in the middle !!!!!!
Crates, an stay'n alive is what this map is about.
Good Luck! YGNI ...........
