I have a couple of troll units in my LOTR armies made up from figures from the Eaglemoss Partwork LOTR series that work well with 28mm troops. But up until now I had no markers for these units other than orcs. The release of the excellent, super value War Troll set from Dark Alliance has solved that.
The markers indicate unit status in my in-house LOTR Fire & Fury based custom rules. Disorder / Breakthrough and Worn / Spent.
Top row based on 40mm metal washer and bottom row on 60mm mdf.
