Buttons backgrounds only may be green (checked) or white (unchecked).
I understand.
Squad efficiency indicated by icon color - yellow, red, gray etc and marks color on 3D screen or map (blink black or yellow)
Platoons color hold for combat hierarchy indication (in next patch).
I think we aren't talking about the same thing - probably it's the language barrier. When I'm talking about efficiency, I mean combat effectiveness of a squad or platoon (not including temporaly effects like suppression). It depends on percentage of losses, percentage of ammunition left, state of heavy weapons and so on... Every time you start a game, you have to select every squad one at a time to see how many men are alive, how much ammunition they have and what is the status of heavy weapons, etc... - all this just to see if they are strong enough for a task you are going to give them. And when there's dozens of squads, this really takes time. If a color indication system (like I proposed in the picture) or something similiar could be done, things would be much easier and less frustating for a player. Hopefully you understand, what I'm trying to explain.
The same was true for battlion/company hierarchy of units, but it will be "fixed" and indicated by color in the next patch, which is a simple, but very good thing! I hope you can come up with some kind of system for losses / combat effectiveness too in the future!
Yes, AI does not any cheat checks on the presence of enemy on firearea and can proactively fired to those areas where your forces is not and can not be.
Yes, and that's good! But look at the timer [see previous picture]!! The possibility that my troops could be there is close to zero. The area is neutral in the beginning of the battle (both A.I. and player know this), so there cannot be neither enemy or friendly troops during the first few minutes of the battle. A.I. should not waste ammunition on areas, where the enemy troops cannot be according to the rules of the game. Later on, however, A.I. should be able to shoot on neutral areas. Conclusion/suggestion: prevent A.I. from shooting artillery on neutral flags only in the beginning of a battle.
