It took no time to exhaust all of the combat related research. Are there weapons behind that research I've not seen yet? I'd like another tier of sharp shooter training. Perhaps it would unlock a new module for the barracks. You'd have to put the training targets module in each barracks. Perhaps make it significant in both research and materials to avoid rolling this out to early in the game. Also, primitive grenades? Research unlocks grenade locker? Your thoughts?
