Maybe we could issue rifles to people living in coastal areas of Britain, then have some sort of lottery to see where you'll be posted on the sea-front.
Then say every fifty people or so maybe a "responsible" person could be issued with a stand-off shore to ship missile, just for those larger targets.
Of course there are those that say we should mine the beaches as well, just to deal with anyone who makes its through the first barrage, personally I think thats a little like overkill, I mean what an earth do they think we have the rifles for??
I expect to see this article in the Littlejohn diatribe any day soon.
