This morning I got the following email from Varusteleka:
Our spies told us that you recently bought some combat equipment. Now we want to give you some tips on how to structure your combat gear based on the line / circle principle.
In layered clothing, each layer has a specific role to play. A very similar model can be applied to other gear, too. Different countries use different terms to describe this but the concept is a similar three-layer model. In Finnish, these layers are called circles but elsewhere they are often referred to as lines. In this article, we go through the basic principles of this kind of thinking and give a few examples of how to use the concept in military and civilian applications.
The full article is here, and is worth reading. Unlike a lot of pieces I've seen on the "line" concept, it differentiates between different roles. E.g., recon scout, infantryman, military police, and civilian.
Other worthwhile articles discussing the different lines of gear include:
