I agree with ya Fork, i think it will be similare to the way Combat Tour is played, any fool who would pleasure himself with killing friendlies would stay in MA and wouldnt be even remotely interested with fitting into a historical frame work. Since gaining rank and doing productive things for a mission will be a part of CT, im sure friendly kills, or even pings could be taken into account when it comes to a promotion or demotion. Friendly pings did happen in real life, heck intense dogfights probably happened that the victor pilot only learned about what he did apon returning to base, thinking, patience, and communication should be rewarded!
