correct ground movement hand signals

[cpetronis]

Today is the day of questions, got another one for your consideration please.
How about ground guide hand signals, is there a British training manual for that? There's a great but very short shot of Polish Shermans embarking for Normandy. In this two second clip an MP from the traffic control squadron is using a specific clenched fist to indicate which track to lock up while motioning with his other hand as the tank turns.
This may sound like a nitpicking type question but if I'm going to be in view of the public while moving armour, I might as well use the proper hand signals if possible. In addition, it would give every member of the team a standardized means of communicating with the driver. I'm sure there was a lot of common sense type signals used as well but I'd rather have something documented if possible.
From my personal experience in the Navy, I noticed the Army and Air Force folks seemed to definitely have codified hand signals when moving vehicles. I had "organizational envy" because us Navy guys just flailed our hands wildly and screamed "Mom-back." Of course that was just my experience. I'm sure there was probably some official training provided by the Navy, I was most likely sick that day. http://www.mapleleafup.net/forums/im...ies/cheers.gif
