player on official servers had a base in a barn with walls and fence blocking doors on the inside. Used 4 hand grenades 2 axes and 5 clips of ak 74 and didn't do anything to the gate or fence walls. His boxes on the inside broke( I lobbed the grenades over the top of the gate to hit the fence from the inside and threw 2 on the outside of the gate) ZERO damage done to gate still pristine as ever.....
