Credit first to CleverchesyTM for backup on what I've been thinking ever since I got the game, and I'm glad to see more than one person around here coming up with imaginative ideas.
War Mode - We can choose this under the combat or construction tab and choose what plane we want to utilize so we can destroy any target we can see that are enemies. In it, we can choose modes of attack for AI planes and tanks and ships, and even choose if we want a squadron to fly with us or not, and what planes are in the squadron. That way, we can choose our strategy and our modes of fight or defense.
Recon Mode/ Electronic Warfare Mode - We should have a kit of Electronic Warfare equipment added, which would help in this mode to call upon the ability to stun radar systems and have strike planes come in behind you and take out the targets, such as small bases or vehicles, and then in Recon all you do is either fly low, fly high, or fly fast and collect data for a later strike on those targets.
Pure War Mode - Essentially the point of this is to not die and to complete missions HQ gives you to complete, the more missions you complete, the more rewards you get, such as stickers and a possibility of having a leading scoreboard with how many days people have lasted and how many missions they've been on and how many targets were taken out.
