Just an example of what a less claustrophobic operations map would look like. In this mission, the Teams would be extracting hostages and rescuing a V.I.P from execution.

And here's what it would look like after planning. Green team taking out the T-55, and then proceeding to the execution square. Red team entering from the north, with Blue team infiltrating the town and providing over-watch for the execution square. 

Meanwhile Yellow Team extracts the hostages, whilst the terrorists are busy working out WTF is happening.

Presumingly, the Red and Blue teams would have secured the VIP prior to the T-55's demise, in case the terrorists forwarded their intentions. Then Green team would have launched into the chaos from the south, allowing Red team to extract the hostage. Blue and Green would have then withdrawn. 

So with all that in mind, I guess any stages of a plan requiring teams to cooperate at certain junctions, will need numbering. Other than that, I think this could work really well. If nothing else, people have a framework to go by.
