I have a briefing I made ages ago which I use as a template. I first made a non-text briefing with the help of Chris' OFP Script Editor and then I filled it up with my own stuff. You can copy the below text and use it as your own template if you wish:

Here we go. Me and my squad is moving in on a town called Davle, close to a vital key-point, the bridge. The Bridge connects the west part of the island from the east. There are another way <a href = "marker:route">here</a>, but that's a major detour.<BR>
Intel reports that Davle should be lightly defended, but there should be a big counterattack since the towns to the west are more concentrated by enemy forces. Also known as: When the tanks rolls in, we're really screwed. But I don't really care. The US army aren't as big as it is bragging about. At least not many of us are posted here on these god damned islands. 10 days top, then I'm either sleeping with the fishes or in a hospital, probably for the rest of my days...

<br>
The mission starts at the <A href = "marker:beach">beach</a>. Those who we're facing, whoever they are, don't know we're comming so the landing should do just fine. We are afraid though that putting in the entire Company would give the enemy enough time to find us, therefor we can only risk one squad to enter Davle, though you may not be many, you have to element of suprise at your hand!<br>
Advance up north and take out the Shilka staioned at <a href = "marker:Davle">Davle</a>. The town should be free from heavy armor and you shouldn't encounter any heavy resistance.<br>
Once you've destroyed the Shilka, Bravo Squad will be parachuted by November 1 and will help you sieze the village. When the village is ours, radio November 2 that'll carry Squads Charlie and Delta and prepare yourself for a counterattack from the <A href = "marker:west">west</a>. Expect Armor and if you can find any kind of explosives or mines, use them!
<br>
If you are forced to retreat, fall back to the <A href = "marker:east">east</a> and try to contact our <A href = "marker:FF">main forces</A>. Last man alive across the bridge must destroy it. Remember: The bridge must at no costs fall to enemy hands! Good Luck!

We will begin the invasion of Nogova from two Directions. <A href = "marker:Davle">Davle</a> and the <A href = "marker:FF">southeast</a> area of the island, around <A href="marker:Okrouhlo">Okrouhlo</a> and <A href="marker:Sedlo">St. Sedlo</A>. Alpha and Bravo Companys invade at the <A href = "marker:FF">southeast</a> part of the island while a small part of Charlie Company head for <A href = "marker:Davle">Davle</a> and the bridge. While Charlie Company holds the bridge to prevent enemy reinforcements, Bravo and Alpha Companys should use most of our forces to advance inland towards <A href="marker:Lipany">Lipany</a>, the capital city. With this city in our hands, securing the rest of the path to Charlie Company should be easy.

Pictures in this section have been taken during the night. For your convenience the pictures have been greatly modified.

The town of Davle is not heavily guarded, it's proteced by small groups of patrolling infantry and BMPs. There is also a Shilka protecting the bridge 24 hours a day.<br>Guards are patrolling the bridge 24 hours a day and can varey in numbers, from 4-12.<br>Study these pictures on Davle taken by our Special Forces Black Ops.

You may find this mission a bit easy, and fairly done without any serious scripting or anything. However, I only made this mission to get the player to understand the situation, so if you feel that the campaign is boring the first few missions, just continue playing and the "real" campaign will get more advance, harder, and hopefully, more entertainment for the player.<br>Also, if you think the pictures in the intel section look funny, it's because they have been taken during the night and have been edited with more intense and for the visual part I added grains. The millitary should be able to add the light back in 1985 shouldn't they?

WARNING: Reading this section may cause serious damage to the entertainment of this mission.
<br>
<br>
If you find this mission hard, try playing it in cadetmode or try to retry the mission. There are differences between the two modes and there are also some random values.
<br>
Do not care about the intel reports of a counterattack from the west, it's bullshit.
<br>
There are a 50 % chance that there'll be a sniper if you play at veteranmode. If he will be there he will be on your right side at the bus stop.
<br>
Stay with your squad. If an AT/LAW soldier gets shot, steal his launcher and take out the Shilka by yourself. Your squad members are quite stupid and will have problems taking out the Shilka on their own.
