What was meant by my statement was...

Let's say you have a platoon of Cobra blue shirts, well you don't need to develope a character story for all 50 Blue Shirts, you focus on the few. In other words if these 50 Cobras are going to blow up a building you can show all 50 parachuting in, you develope the lead Cobra and maybe a few others that have a
key role in blowing up that building thus making them important to the story. Another case is say Gung Ho, Beachhead and Flint are going to steal a Cobra jet well obviously the Jet is important to the story.

Does this clear that statement up? or does it lead to further assumption
