Might I suggest coloured tape for the 2 teams on Friday night?
400 is a LOT of people. And it'd be good to know who's gonna be on which team the next day. Especially when talking plans & tactics on Friday night. Wouldn't want the wrong people eavesdropping or phishing for info!

Also, with ref to the red glowsticks for dead players returning to their HQ at night. Might I also suggest these ( maybe even in a different colour? ) for the marshalls / staff?

I've been to a couple of night-games where the marshalls wore the usual yellow reflective jackets but were still riddled regularly as it was still impossible to see in total darkness.

I think most people will be in their camo's on friday.

You think so? Fair enough. I certainly wasn't planning on being in mine. Wouldn't want to spill beer down them!

I doubt everyone will be in camos on Fri, but armbands is only a suggestion to make things easier. Hardly matters either way I suppose.

I'd assume it would be the first question anyone would ask each other

Armband = not having to ask 400 people and try to remember what team they're all gonna be on!

Well i'm gunna try and learn all the rebels names
Seriously I doubt you'd speak to all 400 people and just a quick your not coalition are you? when someone stands near you will surfice.

Or

we could all get our frequencies and talk over that lol

On the other hand, as you're not going to be briefed until the Saturday morning.. you could just kick back and enjoy yourself.

If you have already been briefed, stay stumn - problem solved.

True.
That sounds like the best plan.
