[cod] [mw] how to pass this spot?

i know it's a dump question but if i went to Google or YouTube i will get spoilers 100%. i also tried to kill the remaining enemies until there were no gunfight except from 1 that I didn't find to kill. i tried to go around and that map is deferent than the one i saw in codm. in codm i remember that there were a bunch of ways to go out but there was none in Cod MW1
