If this interests you, this is what I do when grinding Coveted, start to finish is 3 minutes, not counting loading screens:
- Snipe the guy at the truck
- Reverse the truck to the left, then forward slowly down the hill, on the the right side, until the Cargobob is triggered, then slam on the brakes. If done correctly, it will not trigger the guys down at the container or the 4 guys at the back center of the landing area.
- Snipe the guy all the way to the right hiding behind the truck, the other will probably be behind, ignore him.
- Snipe the guy standing alone
- Snipe the 3 guys surrounding the center truck
By now, the chopper should be pretty close to landing, get in the truck and make your way down the hill
Park parallel to the Cargobob, jump out of the truck, and into the heli. The truck should provide cover on the right, wait a second so the driver door on the heli shuts on the left, protecting you.
Take off, grab the container, and drop it off.
The only tricky part is the helicopter pilot. Depending on your timing of how long you wait for him to get out, he will sometimes pull you out of the chopper if he is still too close to it. I usually only kill 6 guys.
Always make sure you are in a solo invite only session before starting your grinds, because loading back into and out of a solo session is a lot quicker.
