Of course, many times the soldiers themselves are taken out at the alley, so be careful. It's designed to be very snipe-friendly here. You can also come into the alley from around the building for some variety, but most people take the route through the building. In any case, make your decision and then move with some fire in your pants, as you'll need it if the snipers have any sort of ambush put together. Ruins Once you pass out of the alley and into the ruins, there is a very dark, small room to the left.
Snipers love to hide in here, so watch out.
There are also a couple of boxes around to use for temporary cover. Let your escorts scout the ruins out, as the snipers have control of the second level and can snipe from the small walkways there. The hangar is a pretty short way to get from the alley to the garage, but it is frought with danger at the same time. There is a clear field of fire from four sides so you'll have to be careful running through here, but if you make it, you can hide out in the hangar itself for a second to collect yourself and send out a soldier or three to open the garage. You've almost made it, but you have one more major task ahead.
