Hardest Accolade in the game! Epic R.A.P.S. Battle Accolade. | Call of Duty: Black Ops III

The best location to attempt this challenge is in the first fight. The challenge requires you to hit a R.A.P.S. so hack the first set that spawn and if you don't succeed with that one reset. The checkpoint should reset you just before the ceiling falls and the first set of R.A.P.S. spawn.

After you gain control of a R.A.P.S. bring it towards the front and there will be two robots toward the front. These two are the best to destroy because all robots take two passes but these ones are not as aggressive as others. Once you destroy these two the middle row in the ruble has more robots and also where the next wave of R.A.P.S. will attack.

This video shows multiple attempts to show the attempt and reset process. Don't be discouraged and keep trying for this is accolade is very tough.
