What can I say, other than oooops! Sorry, the Hypaspists should be allowed the option of having light armour, but they can't in the AoA list. The reason for the ommision is that I tend to go along with the idea that the Hypaspists (along with most of the rest of Alexanders Macedonian infantry) were trained *either* to fight in a phalanx with a pike (in which case they'd count as a 'Royal Guard' phalanx), or to oprate as light infantry, in which case they'd give up their armour and pike and are covered by the Hypaspist entry in the list.
However, there are plenty of people that think that they operated as a sort of hybrid 'light phalanx', and I really should have remembered to include such an option in the list.
As a house rule, allow the Hypasists to replace their javelins with a thrusting spear and light armour at a cost of +3 points.
