Ooh2g, here is the Arrsepedia page, it is very useful. My advice, though limited in its experience is this. Don't get carried away by the amount of handouts you get. Essentially the Seven Questions can be split in two.
Identifying the Effects you want to have on the enemy
Developing the plan you want to put into action
Remember that orders are just a story that explains to your lads exactly what you want them to do. Nothing more. They just come in a funny format that takes a bit of getting used to. Get your DS to do practice runs extracting orders and doing the Seven Questions. It helps a huge amount. Above all, act confident even if you're not. At MLDP 2 level they're not looking for Clausewitz, though a bit of tactics helps! From the Sandhurst guide to orders
"A man does not have himself killed for Â£37.48 (sic) a day or a petty distinction.
You must speak to the soul in order to electrify him."
Hope this is of some help. Any problems PM me or anyone else who chips in, as they are doubtless much wiser than I.
