On the night of the attack, the Tongans left unmanned the watchtower nearest to the Taliban breach, according to an investigation by the U.S. Central Command.
Either awfully convenient....or a standing practice to which the Taliban tweaked!
Makes one wonder why the Taliban could figure it out but not the Brits or the Marines?
I know it is old fashioned.....but aggressive patrolling and the use of OP/LP's outside the perimeter at night is the very best way of preventing such attacks.
