Ok, so I'm sure it has been discussed about implementing a military system. But if it hasn't, then here it is now.
So what I was thinking is if the game had a military system, in which you could fight for the country, be trained, train, and so much more. I was also thinking of a ranking system, so that when training, military officers would push the soldiers (Enlisted) and give them orders. And enlisted soldiers must respect what the officers command them to do and or what the officers say to them. If the system was to get really in depth, maybe there could be a button that allows people to salute.
I would say more but it's 1 AM at the time I'm posting this.
