Wrangling

[Deimos]

Not to much more to add, The guys/lady's above me have pretty much covered it.

It pretty much comes down to keeping the trooper safe wether it be from people or, obstacles. I'm always on the look out for those people that try to ninja a photo while the trooper is walking past and stop the trooper so the person can take a photo.

When someone is taking a photo I find it best to stand to the side of the trooper but out of the way, this way you can keep a eyes on the troopers back to make sure no one takes anything or puts stickers on (at SN just gone the zombie walk people were very insistent on putting stickers on the troopers and Vader).

As Bids said, when your busy looking after other people you forget about your self. Remember you may not be in costume but you can still dehydrate and become low on energy.

Also a keen knowledge on what the 501st is great. You will get asked questions and there will be loads of them :P if you don't know something you can always point them to someone who might know, don't play mr knowitall and make things up XD
