How many divisions does Rachel Maddow have?

But I think Governor Romney maybe hasn't spent enough time looking at how our military works. You — you mentioned the Navy, for example, and that we have fewer ships than we did in 1916. Well, Governor, we also have fewer horses and bayonets — (laughter) — because the nature of our military's changed. We have these things called aircraft carriers where planes land on them. We have these ships that go underwater, nuclear submarines.

'Ships' don't go underwater.  U Boats do, and in '1916' one sank the Lusitania, eventually resulting in America's entry in WWI.  (They were in use as early as the American Civil War, and Admiral Farragut was famously aware of torpedoes)

Aircraft carriers have been around since the 1920s.  Perhaps someone growing up in Hawaii should be aware of an attack on Pearl Harbor launched from them in 1941.

Want cold hard steel?  The Taliban don't;

A soldier who led a four-man bayonet charge through a hail of Taliban gunfire has been awarded the Military Cross.

That was just last month.  Barack Obama may well have to quit his day job soon, but it won't be to become a military historian.
