Royal Wedding Could Present Problem for British Army

— -- If you've ever been to Buckingham Palace for the changing of the guard, you know protocol for soldiers in Britain is extremely disciplined. So just imagine the strict rules they've received for Prince William and Kate Middleton's wedding.

Did you know protocol calls for a specific way to faint? So what is the "right" way to pass out, if necessary?

"You have to faint to attention," Welsh Guards Major Dai Beven told The Times in Britain. "It will probably involve a broken nose and a whole lot of broken teeth."

All eyes are expected to be on Will and Kate as they wed, but with April temperatures bringing in 70 to 80 degree weather, soldiers should be aware of the possibility of fainting under their red coats, wool pants and bearskin hats so nothing takes away from the royal couple's big day.

Advice from a guard who stood at attention for Prince Charles and Princess Diana's wedding? Keep moving your toes.

"If you are resting on your heels the blood doesn't flow back to the brain," Sgt.-Maj. Billy Mott OBE told The Times in Britain. "You shouldn't faint if you stay alert and keep concentrating. I do equations."

Passing out protocol isn't the only decorum woe soldiers should consider they day of the royal wedding. During the four hours of standing at attention, bathroom breaks are off limits.

It's probably safe to say they should watch their liquid intake that morning.
