Or it can be something like...

Person A: Hey, what do you think we should do?
Person B: Maybe if we throw a grenade off to the side to create a diversion.
Person C: Right, right, maybe some fire crackers. Something that can imitate gun fire and throw it over the side of the building.
Person A: Okay! I think this can work. Where will we be running?
Person C: Running through the alleys might be better, to stay out of direct gunfire. We can use Comm support to help guide us there since the route isn't very organized.

Holy cow, suddenly we have a pretty okay plan with only a few posts and without wasting time on IC chatter. Which was the original idea behind it.
