Syntagma? Taxis?

[Che Roriniho]

Hey there, me again. I'm currently working on a manual for EB (Unofficial, and yes I know there's another one, but this will be a more portable downloadable pdf), and I'm doing the formations for all factions, and I'm now upto Makedonia (So far I've only done Romani (5 formations in Total), and they aren't QUITE complete), and I've found a source for a Makedonian army layout, but I'm troubled by a few things.

First, here's what I'm working from:



The problem I'm having is this: What are 'Syntagma' towards the left of the Phalanx, and 'Taxis', which are on the right? I have most of the others sorted.

Secondarily, I'm Guessing Toxotoi Kretikoi would be often used, but where would hese be put? In the Allied Light Infantry? Similarily the Thrakioi Peltasai. I'm guessing the latter would go on the flanks.

Any help greatly appreciated.

EDIT: I am aware that the Hypaspits are actually Heavy infantry.
