Roadblocks destroyed by a few shots of .50

Now fully shoveled roadblocks can be destroyed by a few shots of .50
For 10 meter, its 6 shots, and around 3-4 to remove the base, and for 5 meter its 4 shots, and 2 for the base.

Is this an intentional change?

Tested on Fallujah, but ive been told it works on every ins map.
