Can't destroy barrels or fusion cores in SWAT?

Why did they remove this? With the new update you can no longer blow up the explosive barrels around the map. The barrels were put into specific areas to give a little danger to highly strategic points. It also made you have to be wary of your surroundings, but now you can just run by or camp these places because you can’t blow up the barrels.

I don’t recall ever being able to in the first place. But it’s usually easier to just headshot someone so I’ve never tried.
