Now this may sound a bit weird coming from me, but I hope Lego doesn't make a military theme. No it's not for that BS "anti-violence" policy. It’s because an army theme would kill off custom army making. Think about it if Lego released a military theme almost everybody would flock to it and purchase multiples of each set to build up “their” army. From then on most armies would basically be the same with each having the same soldiers weapons, and vehicles.
I hope you guys get the jist of what I’m saying.
