I'm pretty deep into a Baktrian campaign at the moment and I'm loving it.
I will be making an AAR out of it soon (once I reunite Alexandros's conquests) and I want to play as realistically as possible.

I love Hellenikoi Kataphraktoi and so I usually try and field a large contingent of them in each army, but I don't know how to use them to their greatest effect. Should I use them in conjunction with lighter cavalry? Should I flank the enemy phalanxes with them all at once and use them as a hammer against my anvil or should I use them as individual units?

Any advice at all is welcome, even if you don't answer these questions.
