    Its pretty simple and takes like 1 minitue go on spec ops solo or co-op and on the mission Breach and Clear (something like that) at the beggining with your m4 carbine just use your greanade launchers right in the middle

    adamrulzWow Epsilon Factor, a thumbs down because you don't know to press left on the D-pad to get the grenade launcher ready... press L on the d-pad, then hold X to breach. Got it on my 4th attempt (took less than 2 mins) FANTASTIC GUIDE!! +1, THANKS!!

    Basically, you have to kill 4 enemies with 4 shots during a slow-mo breach in Single Player or Spec Ops. In the video below this is done in Single Player on the mission "The only easy day...was yesterday", on Veteran, although difficulty does not affect it. You can kill them in UNDER 4 shots, but not exceed the four shots. I prefer not to use the M203 Grenade Launcher because this is the first chance you have to get this achievement and the presence of hostages makes this difficult to aim.

    I went on wet work with a partner (There may not be enough enemies if you are alone). The first room to breach has an AT4 along the way leaning against some boxes. Pick that up, go to the far breach door and fire the rocket in the center of the room. You'll fail the mission for killing hostages, but the achievement comes up and it's pretty fun at the same time
