Though I now have some experience with this game (e.g. I can beat the comp at both normal and challenging), I still have trouble with developing my military effectively. Sometimes I fall dangerously behind, other times I develop some weapons but sometimes they aren't as effective as they should be. Also, there are a bunch of weapons to choose from and I'm still uncertain if I should specialize or try to balance them out. My current strategy is to have one primary set of weapons and a secondary set, but its time consuming researching them all. Any hints please?
