They Couldnt even get close to GHQ, unless ofcourse there is somthing happening from inside, ie: some1 with access to GHQ selling out. But there are no such reports or any sign of such happening so its out of question.
The best these idiots could do was bomb the first check post and than got smashed.....Armys response was massive.. The fact that they couldnt detonate their bomb in the car means quite alot.
Their plan was to blast their way past check post and bomb GHQ or something close to it.
