War with Friends

Hi all, this is my first map, I made it as a duel, with some closs real life friends, I could seriously use some advice on it and some help, all units are reskinned they all have the same stats, ALSO the middle part of the map (SpaceX) Has a super nuke that sends weapons of mass destruction flying through the sky, furthermore currently the engineers are supposed to transport the fortifications to the battlefield but, It wont work so please give me some time to fix it, but I was hoping to make a way to build a defensive line with real building, (Also there currently is no air defence units yet or anti super missile units YET).
Its called "War with friends" by Nerdy General

Also please reply with comments, concerns and opinions, also start with the max money and don't play the middle country (SpaceX)
