How historically accurate do you need to be

[Erpingham]

What I was thinking more was where I have seen combinations of colours - like my red cross on blue - which don't work either aesthetically or heraldically.
By looking at historic examples there are quite a few simple designs which are still easy to do but which add a bit more variation than the more common fesses, bends etc.

We are in agreement here. I might make arms up, but I follow the rules and spend time looking at real arms in my heraldry books or online for inspiration. I'm afraid I have to confess, I am dreadful at animal charges. I should have far more lions, eagles and so on than I do

I find animal charges (in 15mm anyway) more forgiving than many of the straight line designs. My eye gets drawn to wobbly or uneven supposedly straight lines more than the animals which have the advantage that they are supposed to be wobbly and uneven.

Scale is your friend again here to a degree...

My animals tend to look like they have been in a Cronenberg movie

I think it is having the entity structured and operating tactically as such that comes before the naming.

So, there may be a Chatti warband but where are their accompanying skirmishers and cavalry (if any) and are they all under the command of a Chatti chieftain rather than scattered about the force?

And whether the Tenth legion gets a bonus for being Caesar's Tenth is optional as long as it can be identified as a body of up to 5,000 men under the command of a legate and depending upon your level of abstraction organised into cohort sized units.

P.S. If our noble editor could see what I've tried to paint on the shields of my 6mm hoplites, he would be very cross.
