Let's talk briefings.
One of the most immersive factor of a scenario are the briefings. The scenario designer should give as much time creating the briefings for a scenario as he does in creating the scenario.
So, what goes into a briefing? Load up the briefing with what you like to see in them.
For me personally, I want to see the general and specific information each commander would get for the side specific briefings and the overall operational situation for the scenario description. How much information you give is totally dependent on the person writing them.
One of the main issues to determine is whether you tell the truth or you mislead the gamer with the briefings.
There is a single reason for choosing which direction to go, surprise. If you want an out of the box 'Aw ****' moment when something comes out of left field those are greatly supported by you not telling the truth. For instance stating that a Motorized Rifle Division is operating in the area, inferring you are facing infantry, only to find out you are facing a Guards Tank Division. That surprise works exactly one time; the first time it's played.
Which just coincidentally happens to be the same number of times a major surprise works to begin with. So, if you are creating a situation with a major twist in it the briefing can be a part of the tool to intensify that surprise.
For the most part, I tell the truth in the briefings. What I expect to see, while telling the truth, that there are things we actually don't know. We don't know exactly who or what we are facing. We aren't 100% sure of where they may appear. We don't know exactly when our reinforcements may show up. Those are all truthful without being exact down to every detail.
Hope this helps.
