Hi OB,
Well, when I designed my armies I did so with PK in mind. So, 4 stand units are the norm (though it doesn't matter because we mark casualties with a marker rather than stand removal – PK is versatile that way) but 4 stand units of western knights would, at figure scale, be huge – and they are generally able to hold more than their own against superior numbers of, say, ghulams due to heavier weapons, couched lance, and physical butchness (or so the history tells us). So I gave all of my heavy cavalry (including the Saracen stuff to be fair) two flags so that they could be 2 stand units.
Of course, I did pack my stands to make them look meaty.A heavy cavalry unit, based on four 60mm frontage x 90mm depth stands, has 18 figures – so even halved they are 9 strong. The pic below shows units of Saracen heavy cavalry (I have 6, which in retrospect is too many) – the deep bases actually allow the impression of two ranks, more packed, with less figures: I thought that was quite a clever idea, and I don't have many!
When coming on together theylook the business (IMHO)
BTW, the '6' key on my computer is typing '3' (luckily I also have a touch screen keyboard which works). Does anyone know if I can change this or is it a hardware fault?
