Yeah, the landless mercenary without noble origins is the biggest threat to their thrones. What a bunch of jokers.

EDIT: How Can I see How much my RTR is?
I believe that set is used by the Rangers of the Clarion Call, isn't it? You can join their knighthood if you want their armor, although I believe you may be able to buy it from a shop on rare occasion.
You can check your RTR by going to Reports, and then checking your Character Report. It'll list your current status in the realm (Mercenary Captain/Vassal under which kingdom) and the knighthood you belong to, if any.
