can anyone identify this chain?

This is the chain on my Stihl 031AV. I have very little knowledge about chain types and design. Can any help identify this chain type and what kind of cutting it's used for? Thanks (one tooth is green) Sorry about the picture quality.

The green link signifies safety chain, if the funny looking guard links were not obvious. I'm looking at a Stihl catalog and the closest visual is RM2.

Yeah, I have a Stihl catalog too. My chain looks similiar to RM2. I guess this chain design is for low kickback.
