We've recently be building our regiment as players and being limited to Infantry by our GM were tryign to decide between Light, Line, Drop and Seige and quickly came to the conclusion that Light were simply inferior to all of the others.
They get a useful skill, but it's one that you can pick up elsewhere at character gen, but their talent isn't so useful and their equipment is massively inferior to all the others.
My feeling was that Light Infantry should either have been given some extra gear or cost only 1 point.
The starting with a flak vest and helm maybe theamatic for the like of Catachans but combined with their toughness penalty it does seem to want to make the PC's very fragile.
In the end we went with Line Infantry; as they seemed the most adaptable to the roles we each wanted to play.
But what do you guys think about the cost balance in regiment creation?
