Land and Sea Combat icons?

[Slippery Jim]

I can't find this anywhere, so ...

During combat I see all of these little round icons appear over the health bar of myself and my opponents. In some cases they are intuitive, such as when my ship is on fire, and there is a little count-down timer around the perimeter of the icon, then it disappears.

OK, fine. Cool.

But is there a guide somewhere that lists all of these icons and what they mean? Because I'd like to know. There must be some reason we are meant to know what these icons are telling us ....
