Also you say 2 elites, but I've got grunts, 1 elite and 2 shield dudes. Also, none of the grunts jump on the turrets after I've taken out the gunners. Thanks.
You get the achievement for killing them all without them shooting back. You will know when they see you because the music starts. Took me a few tries, try on Easy.
