I don't know if it will work for you but this i how i got it. on seirra 117 when you get to the riverrun down and take out the brute and grunts to the right. somewhere in the area should be a .50 cal. turret pick it up and wait for the phantom. when it comes start shooting the gun on the front right away. when i destroyed the gun it gave me the "used car salesman". i dont know if it was a glitch or if it wil work for you, but it is worth a shot and pretty easy to do.

Easiest is on Ark, you get a tank, and theres lots of Spectres running around with 3+ brutes in them. Pop one with the cannon and poof, achievement unlocked.

thanks for the help but on the arc i tried using a tank on a spectre and i nver get achievemnt and that glitch doesnt seem to work either, any other ideas

It should work as long as there's at least 3 brutes in the spectre. If you're doing it on easy, there'll only be 2.

i might just give up lol im playing on normal tried the ark, with scripion blew up a spectre didnt work, used a s. laser on a spectre didnt work, tried all the glitches on the phantom didnt work i dont know what else to do

thanks for all the help haha i did the blow up a turret on a phantom on sierra 117 on legendary and it worked lol idk why i had to do it on legendary but i got it thanks again

use a turrent

wait so is that turret at the start were u see the first phantom or were u those 2 pelicans blow up randomly???

nvm i just used a plasma grenade! yay! i got security helmet and katana!

Does this have to be on legendary? I keep destroying phantom turrets on normal, no luck. Do you need to finish the level afterwards?

thanks for all the help i did the blow up a turret on a phantom on sierra 117 on legendary and it worked .
