Maybe in the Gulf war when Iraq used schools,hospitals, Museums and any civiilian buildings in the hope that that wouldn't be attached...
There was a rouge solider or ex solider that stole a tank in America.....he went beserk and smashed every thing in his path until he got stuck on the central steel deciding barrier on one of your motorways... An armed policeman then jumped on it and shot him dead through the turret door.... You can watch it on ytube.....
I think anything is possible nowadays....There is always a way around security now we reliey more and more from electronic surveillance ... A 16 year old English computer wizz loner hacked into America's Millitary computers a few years ago...form what I gather it wasn't to hard.... You can't tell me that Russia, North Korea or China carn't are unable to be even better at it.... Full security can never ever exist..... Its not in any country interest to have systems that carn't be exploited either ,I'm sad to say...... :(
