ok my 1st suggestion ever, i hope you'll like it Options

[DeE]

1st something like good old MAAS, but more new WEA styled.
an airship which won't be a super deadly killing weapon, but something like support station ... "guardian angel above your troops" healing them, helping them target distant enemies, transporting them, protecting, shielding and even recovering (ok i think it's too much)
it will have a defensive capabilities but won't survive for too long without help.

2nd another aerial something.
A counterpart to an airship something like gunship circling area and bombarding. It will come with some AA drones and something like stratofighter upgrade allowing it to go up and "off the screen" and then descend on the location you select (will need to refuel and rearm) or not it's up to you but i thing it will be too much without rearming and refueling.

i'm sorry for my english

P.S. if you like my ideas i can think about more things just let me know.
