Halo: Reach achievement hunting help

Hey there fellow Spartans,
I’m in dire straits when it comes to trying to get this one specific achievement for Reach that I haven’t been able to get for nearly 5 years (Granted it’s been awhile since I’ve played Reach). Anywho the achievement is called “You blew it up!” And it’s apart of the Defiant Map Pack. It’s worth 13G and has bothered my mild OCD with numbers ever since I unlocked its corresponding partner worth 42G. Any help with this would be greatly appreciated and I’d be more than happy to help whoever helps me achievement hunt for what they need to get on Reach in return.

hey add me @ Katsensual, would be down to help do this. I have 3 controllers. Add and message me to pick a time.
