regarding the aiel o think they should be mostly skirmish units weak to bow/crossbow fire when in the open.
they could have the ability to hide almost anywhere and so the basic aiel tactics would be a harass/ambush type strategy.

they would have strong spear units no swordsmen(duh) and normal archery units no cavalry though.

they would also be weak to heavy cavalry if they were charged but as i said, skirmish units with great stealth.
