I just noticed that there is now a ground defences section of the AI page on the forgeworld site-

http://www.forgeworld.co.uk/acatalog..._DEFENCES.html

(sorry if it has been mentioned but it's news to me)

And i have some questions, is there any in-game difference between the hydra and hydra platforms, and approximately how many hydras would one need in a game (say it was a 200 point game with ground defences)

Thanks!
