Well you learn something every day, so the cliché says. Today I learned that the military use huge inflatable tanks in their exercises. And not only that: one of them has gone missing, blown away in the U.K.'s recent gales. The BBC has the story:-
On Monday a military spokesman said they were anxious to hear from anyone who may have woken during the morning to find a tank in their garden.
It made me wonder why they don't use these cheap substitutes in battle to scare the enemy; perhaps they're too easy to blow up.
