Call of Duty: Modern Warfare 2 (2009)

Both manageable if you've made it this far already on Vet. And the end of Wolverines can be made quite a bit easier by ignoring the advice given to you over the radio. When the second gunship shows up and you are told to run to Nate's and get the Stinger, don't. Go prone inside and use the MG to light up the chopper whenever it cruises past the window. Eventually it'll go down in flames, and the convoy will arrive. Because you didn't run over to Nate's, you're only a stone's throw from the convoy, with no Russians in between.
