Can PC Stop a Tank?

This funny story from Britain has the Army worried about it's Challnger tanks to new EU rules. The article explains:

Defence chiefs are fighting to prevent the Army's tanks being stopped in their tracks by the introduction of a European directive on vibration and noise at work.
The Control of Vibration at Work Regulations and the Control of Noise at Work Regulations have left officers scrambling to discover if the military's armoured vehicles break the rules.
But with a slim chance of reducing vibrations in a Challenger 2 tank and the Warrior armoured vehicles, the Ministry of Defence will be seeking an exemption from the rules by invoking an "opt-out" clause. Soldiers who travel in the back of tanks and are subjected to substantial jolts and constant noise will have to suffer the discomforts until at least 2010 when the regulations become law.
