Operation Firestorm hiding inside rock

So on my last match in Operation Firestorm I got killed and destroying our tanks in a suspicious by an enemy squad player. Came to finding out they where hiding inside of a rock and you couldn't defeat them because somehow the colliders  was protect them since they where inside it, I did try to reproduce the exploit with out success but I leave the exactly location with the image attached to this post and hoping the dev team looks at this and fixes this issue
