Unit Features - Explained

What are the chances of getting the "Manual" updated so unit features are explained. Old/Original features like "Patrol" for aircraft vs "Attack"... and how AA guns work, when do they fire at aircraft that fly overhead.

More recent "Special Features" such as the new icon which appears after Paratrooper have been deployed. The icon that appears overhead with 4 arrows pointing toward its' centre which I can only guess means "round-up or reassemble" . Such an action would make sense after having troops thrown all over the countryside after an air drop needing time to find their units once again. But since there is no easily found description of this mystery symbol and function... guessing is all we've got.

There is a "Manual" thread which goes over the stats of each unit but fails to provide meaningful details about unit abilities. For "Patrol" for example, it simply states that the Patrolling unit attacks regularly, as opposed to giving into that Air Units on Patrol attack every 15minues with 1/4 of their full strength.

So much talk about new players being able to "get up to speed" ASAP... something like this would go a long way.
