Requirements, what a strong word. Suggestions? Not strong enough damn it. 
Now what I think would be extremely useful for everyone, if any of my crazy plans come to anything like fruition.
We all know about guns and things, so no need to go there. Other stuff =
Watch
Pencil and Paper
Compass
Tin Mug
Anyone who brings mobile Early Grey making facilities will score extra browny points to be sure. 
flask of tea would suffice but there are cooler ways... Though there could be some rule-y things about stoves and boiling liquids in game.
OK, tin mug goes on the list. 
The brits brewed up at Husky but I would just carry a flask, save the buggering around. And what happens if ze Germans see you while you're brewing up and you get ambushed! Then it'd be a waste of good tea (shooting offence).
As for watches! If you look in Argos they sell a watch for about a fiver which looks period and apparently all the reenactors wear it!

Show me a man who will jump out of an airplane, and I'll show you a man who will fight!
General James M. Gavin
CRY HAVOC AND LET LOOSE THE DOGS OF WAR
That's the watch I got.
even smashed the front a bit, by accident 
, so now it's battle worn.
Brewing tea whilst ambushed by Germans? Now that would be an event to remember. 
Not if you spilt the tea

Well, as long as they brought the biscuits!
"Will you stop talking about the war!!"
"What, you started it!"
"We did NOT start it!"
"Yes you did, you invaded Poland..."
Not if you spilt the tea
Spill the Tea? Spill the Tea?
We're British damn it, they'd need howitzers to make us spill the tea. 
Right chaps.
Time is rapidly approaching so we need to sort out the stuff for these sneeky bombs and such, because I cannot aford to buy everything myself. 
Now we need
Fishing line
Square batteries (9 volt)
'2-core' electic wire stuff
wooden tent pegs
wooden cothes pegs.
Now we have wooden clothes pegs, and I think we can make wooden tent pegs by whittling a couple of sticks frankly (as our tent pegs ill be in, well, the tents)
So that leaves
Fishing Line
Square Batteries
2 core cable
It also looks like we are down to four chaps again for the Brits so if anyone of us has a huge box of square batteries in the shed (etc etc) let us know before I dish out 'procurement' orders.
Also Lipton and Horus, I have ordered you 2 grenades and a smoke each. I thought it would be presumptuous to order some for Jeremy, but you too I don't care about that much.
And Mindham, get that commando jumper damn your eyes.
