It would seem that air and cruise attacks should have the ability cause soldier casualties. In theory, airstrikes and cruise missles could be sent by the attacking nation to concentrait on troop positions, barracks etc. Even causing tank destruction would suggest loss of sodiers, both in the tanks themselves and in Infantry who usually accompany tanks.
There could be some tech, infra and perhaps improvement/wonder requirements in order to enable troop destruction. For instance If a nation qualifies for L3 aircraft and has a satelite improvement, air attacks would cause a ratio of soldier loss.
IMHO it would add a little somethin.
