MGS V: Ground Zeroes - Destroy The Anti-Air Emplacements (5)

The harder route is just to manually set up C4 around the base. Just complete the mission and unlock the RPG, then you can lit em all up from the starting point instead for a perfect score.
Think I'm gonna stop here, Déjà Vu and Jamais Vu are missions I never cared for. Would much rather gun down missions in Afghanistan and Africa in The Phantom Pain as Raiden/Solid lol.
