The, Pants, Party
You will be introduced to this during the tutorial (the "Retrieve the Ironheart" operation mentioned in the description, which does not count). When doing any Intercept Battle (see I Can See the Future of the Colossi (40G) for more info on these), you'll want to find and aim for any part of the Colossi that lights up blue when you shoot it. Keep shooting until it then begins to flash yellow when shooting it, and at that time you want to use your grappling hook with 
to latch on to the armor piece flashing yellow. Once you have mounted the Colossi, begin attacking it with 
and any time it starts to move wildly to try and knock you off, hold 
to steady yourself. Once you strike it a few times, the piece will break off. Repeat this a second time to get the achievement.
Note: I got this during a single encounter so I'm not sure if it's cumulative between multiple encounters or not, but the wording of the achievement doesn't seem to indicate that it has to be done against one enemy.
