Is this an official joke thread?
Let me see, foot patrols wearing snowshoes - so the bad guy pops up, lets off a few rounds, then scoots off chortling in his Adidas flip flops while the foot patrol waddle after him... Hovercraft, flail tanks turning every road surface into a goat track, vehicles with wheels on the end of legs (you'd be able to drive that down any standard motorway sized road then - might not fit through the middle of a village though). Meanwhile GPS and Mobile phones go off the air, while Johnny Afghan wonders why his TV switches to Postman Pat whenever a landy goes past.
My guess is the next big idea will turn out to be an unintentional rip off from Thunderbirds, perhaps using the Mole?
I think I've figured out why nobody seems to be using Pprune as a think tank....
