Yeah, Toughness value as a letter is the give away.
I notice that the better half-orc fighters have Toughness C (which would be 4 in second edition), suggesting that they've a stronger strain of orcish heritage.
Still trying to get my Gyokurinti's Raiders Chaos Hobgoblin force based on the forces of fantasy booklet painted
I had a good look through
your thread last night: great stuff! I'm in the process of basing most of my solid-based hobgoblins for Hordes of the Things (and Dragon Rampant). I'll base up most of the slotta-based ones individually for skirmish (and DR casualty management). The solid=multibase/slotta=individual formula is also what I'm using with my slann. The half-orcs are individuals all the way, though!
