Here are 2 saves that I made to make things a little easier going for your platinum trophy... The platinum save only requires 1 kill of each respective trophy to earn that trophy.
Use the F-22 Raptor save first and replay mission 11 to unlock "Transmission Ends"... then continue playing mission 12 to unlock "5th Generation".
Now load the Plat save and go to mission 14 to get "Aerial Photographer"... After that trophy pops you can re-load the plat save just to be safe and then continue campaign to unlock all difficulty trophies and "Stain Removal".
Here Is The Trophy Guide.
