There is a section part way through Chapter 4 where you go round to flank some enemies on turrets and then take the turret. Your squadmates tell you to shoot out a window to bury the enemy in sand but if you don't then the enemies keep coming.
There are multiple explosive objects in this area to help you get "Adapt and Overcome" and also endless enemies rappelling from an opening in front of you to help get "Airspace Control".
If you run out of explosive objects simply die or reload the last checkpoint and you should have both these trophies in no time.
