Put the four wingman orders on buttons or keys, you can reach and use easy.
The wingmen in OFF are not just decoration - they really follow your orders, and can be a great help.
R: Return = the order to make them re-assemble, or to make them break off a fight
H: Help = pressed once, it seems to call for your personal wingman (wing 1) only. He will stay near you
most of the time anyway, if possible. When you press "Help", he will attack the enemy next to you.
I had the impression, that, when I pressed "Help" more often, the other wingmen helped me too.
S: Split = the order to make them take more distance to each other - useful, when your flight gets
attacked from behind
A: Attack = an order, you can use two ways. You can mark a target on your TAC - when you press "Attack"
now, you will make them attack that single target. That also, when you do a ground attack: switch TAC
to buildings or vehicles, mark one, and press Attack.
If you don't mark any targets and press attack, they will attack enemies, which are so close, that they
appear red in the TAC - probably the closest of them.
(But careful - I used it sometimes to check, if enemies where near I hadn't seen. But when I flew low, they
would suddenly attack ground targets.)
Especially the Help button often saved my bum.
The Attack button is also useful to make them attack the highest flying opponents (for their own sake) -
you just mark the top one.
A last note: take care of your wingmates, help them, if you can, and they'll help you. And you want to bring
them back home with you - someone must be witness for your claims.
