Repair and Update Units must be together

[BuddyGrant]

You can use current leaders on naval units if you like.

We thought about earlier adding air and naval leaders, but the beta team voted against it. Technically it's not a big deal.

The leaders mainly are used to give a max morale bonus.

I would love it if adding naval *AND* air leaders could be an option for some players, even if that was not the default game setting. Currently I find it a tedious administrative exercise to always keep a ground unit w/ leader nearby my most important air fleets.
