This little project has been limping along for a month or two...now with Warhammer 40k, Planetstrike I have no excuse but to finish it up. I'll have to order the Rail Guns for the Defense Pods and perhaps take advantage of the forthcoming Gun Drone spru as well.
Essentially, the Defense Base will consist of the elements shown above with a defense line and minefield markers to come soon. There will also be another Hanger as well as a ruined one, just for fun. Okay, now I've opened my big mouth and put in print...no turning back!
