I took a huge gamble the other day and repainted a unit of the III Gallica to represent the 16th Flavia Firma. Alanicus's army of Anatolia is made up of Vexillations of the VI Farrata and the XVI Flavia Firma, so after a long time thinking about it, I decided to bite the bullet and do it. They used to be the sandy yellow seen in older photos but now they look completely different in a madder red. I gave them a very Caesarian motif to match their older style shields .
I still have three cohorts of III Gallica (a whole legion in the game) so I don't think they will be missed that much and I'm glad I went for it. The more variety in the colours and designs within the armies the better I think.
The colour and design was influenced by the unit of Evocati I had painted earlier, seen in the background with the white plumes.
