Ari, what I meant was the first line, where you normally write your team members in.
If you don't have any, try "ground troops military defense 427" for example - the "mil.def."
is one of the locations which are mentioned in briefing; could also be "observation balloon
at balloon base 623". But chances to get that confirmed seem to be small.
Still though - there must be a reason why you get the form; so you could try.
I often don't get a form, even when I started with wingmen, but lost them, before I shot
down a craft.
You will also find, that some claims remain unconfirmed or get refused. That's how it was.
If you want it easier, you can always follow UncleAl's advice.
