So there I was, flying into a very lightly defended field. The town and field were both deacked and the VH was soft. Only a single GV out. No enemy aircraft up. The three fighters trying to white flag the last few buildings in town all ran out of ammo. Thankfully we were relieved on station by... 3 C-47s

It occured to me this happens all the time.
Yes there is a mission editor, but many base grabs simply develop spontaneously. In these cases there is no leader or msn vox and any coordination takes place via pleas for X or Y at base Z over country channel.
It would be nice for people interested in base takes to have the option of selecting a target field. (Available in preferences) IE: Player X wants to help the efforts at A15. He selects A15 as his target and a "Committed Assets" page comes up. Player X sees a list of players who have already selected A15 as their target (broken down by perk category). Also, player X would be able to see their aircraft/vehicle type here as well. When player X takes off he shows up on the list just like everyone else till he lands/towers out. Each player present on the list would have a text box next to his name where he could update intentions or requests pertinent to the target. Player X can now join the fight confident that he will effectively be contributing to the fight as opposed to being the 10th M3 to arrive at a town occupied by tanks.
