So I if you are in the capaign and have done close as I did, then heres a good spot in the fourth mission where you can knock this out as well and quick. Its when you get to the dock from the left at the beginning.
Take out the enemies when the reinforments come, so you dont get spotted, plant a tnt, bust the tank, create a save somewhere safe and close (look at video), satchel that sucker, rinse and repeat.
Literally take out all the enemies in that area. The AI enemies are too far to hear the explosions, if you have taken out the necessary enemies.
Honestly took me about 10-15 mins, but I did have 5 or so under my belt already. Just another solution.
Cheevo popped but I guess XboneDVR doesnt pick it up. :\
